How to install the application

Kaspersky Internet Security is installed to your computer in interactive mode using the Setup and Removal Wizard.

The Wizard consists of a series of pages (steps), which you can navigate through by clicking the Back and Next buttons. To close the Wizard after it finishes, click the Done button. To stop the Wizard's activity at any step of installation, close the Wizard window.

The number and sequence of steps in the Wizard depend on the region where you install the application. In some regions, the Wizard prompts you to accept additional agreements regarding how your personal data is processed, and to confirm that you are at least 16 years of age.

If the application will be used to protect more than one computer (with the maximum number of computers defined by the terms of the End User License Agreement), the installation procedure will be identical on all computers.

To install Kaspersky Internet Security on your computer,

On the installation CD, run the file with the .exe extension.

The application is then installed using the standard Setup and Removal Wizard.

In some regions, the installation CD does not include the application installation package. The installation CD contains only the autorun file. When this file is executed, the application download window opens.

How to install the application using the autorun file

To install Kaspersky Internet Security, you can also download an installation package from the Internet. In this case, the Wizard displays several additional installation steps for some localization languages.

Along with the application, plug-ins for browsers are installed to ensure safe Internet browsing.

When you run audio and video recording or playback applications for the first time since installation of Kaspersky Internet Security, audio and video playback or recording may be interrupted. This is required to enable the functionality that controls access by applications to sound recording devices. The system service that controls audio hardware is restarted when Kaspersky Internet Security is run for the first time.

Kaspersky Internet Security is installed together with the Kaspersky VPN Secure Connection application intended for establishing a secure connection via Virtual Private Network (VPN). You can remove Kaspersky VPN Secure Connection separately from Kaspersky Internet Security. If the use of VPN is prohibited in your country, Kaspersky VPN Secure Connection is not installed.

Checking for a newer version of the application

Before installation, the Setup Wizard checks the update servers of Kaspersky for a newer version of Kaspersky Internet Security.

If the Wizard does not detect any newer version of the application on Kaspersky update servers, it starts installing the current version.

If the Setup Wizard detects a newer version of Kaspersky Internet Security on Kaspersky update servers, it prompts you to download and install it on your computer. It is recommended that you install the new version of the application, because newer versions include more enhancements that allow you to ensure more reliable protection of your computer. If you refuse to install the new version, the Wizard starts installing the current version of the application. If you agree to install the new version of the application, the Wizard copies the files from the installation package to your computer and starts installing the new version.

Starting installation of the application

During this step, the Wizard prompts you to install the application.

To proceed with installation, click the Continue button.

Depending on the installation type and the localization language, during this step the Wizard may prompt you to view the End User License Agreement concluded between you and Kaspersky, and ask whether you want to participate in Kaspersky Security Network.

Reviewing the End User License Agreement

This step of the Wizard is displayed for some localization languages when installing Kaspersky Internet Security from an installation package downloaded from the Internet.

During this step, the Wizard prompts you to review the End User License Agreement concluded between you and Kaspersky.

Read the End User License Agreement thoroughly and, if you agree with all of its terms, click the Accept button. Installation of the application to your computer then continues.

If the terms of the End User License Agreement are not accepted, the application will not be installed.

In some regions, you must also accept the terms of the Privacy Policy to continue installation of the application.

Kaspersky Security Network Statement

During this step, the Wizard invites you to participate in Kaspersky Security Network. Participation in the program involves sending information about threats detected on your computer, running applications, and downloaded signed applications, as well as information about your operating system, to AO Kaspersky Lab. No personal data received from you is collected, processed, or stored.

Review the Kaspersky Security Network Statement. If you accept all of its terms, in the Wizard window, click the Accept button.

If you do not want to participate in Kaspersky Security Network, click the Decline button.

After you accept or decline participation in Kaspersky Security Network, application installation continues.

In some application versions, the Kaspersky Security Network Statement includes information about personal data processing.

Installing the application

Some versions of Kaspersky Internet Security are distributed by subscription, and a password received from the service provider must be entered before installation.

After you enter the password, application installation starts.

Installation of the application can take some time. Wait for it to finish.

Upon installation completion, the Setup Wizard automatically proceeds to the next step.

Checks during application installation

Kaspersky Internet Security performs several checks during installation. These checks may detect the following problems:

• Non-compliance of the operating system with the software requirements. During installation the Wizard checks the following conditions:
  • Whether the operating system and Service Pack meet the software requirements
  • All the required applications are available
  • The amount of free disk space is enough for installation
  • The user installing the application has administrator privileges

  If any of the above-listed requirements is not met, a corresponding notification is displayed.

• Presence of incompatible applications on the computer. If any incompatible applications are detected, they are displayed in a list on the screen, and you will be prompted to remove them. You are advised to manually remove any applications that Kaspersky Internet Security cannot remove automatically. When removing incompatible applications, you will need to restart your operating system, after which installation of Kaspersky Internet Security continues automatically.

Installing Kaspersky Password Manager

Before completing the installation, Kaspersky Internet Security also prompts you to install Kaspersky Password Manager to protect your passwords. The installation of Kaspersky Password Manager may continue after finishing the installation of Kaspersky Internet Security, there is no separate notification about completing the installation of Kaspersky Password Manager.

Recommended settings

At this step, you can view and change the Kaspersky Internet Security settings that Kaspersky experts advise you to enable before beginning to use the application.

To change the recommended settings:

1. Select which settings you want to enable or disable:
   • If you frequently download and install applications from the Internet, leave the Turn on protection against ads to install only desired software and block additional installations check box selected. This will help you prevent the installation of unnecessary applications.
   • Leave the Delete malicious tools, adware, auto-dialers and suspicious packers check box selected if you want the application to delete these objects.
   • If you frequently install new applications, leave the Detect other software that can be used by criminals to damage your computer or personal data check box selected. This will help you detect applications that can be used to damage your computer or data.
   • To learn about the new and main capabilities of the application, leave the Take a tour through the application features check box selected.

   If you do not want to enable Kaspersky's recommended settings, clear the relevant boxes.

2. Click the Apply button.

Completing installation

During this step, the Wizard informs you of the completion of application installation.

Click the Done button.

All necessary application components will be automatically started immediately after installation is complete.

In some cases, you may need to restart your operating system to complete installation.

Activating the application

The Activation Wizard is started at the first launch of Kaspersky Internet Security.

Activation is the process of making operational a fully functional version of the application for a specified period of time.

The following options for Kaspersky Internet Security activation are offered:

• Activate application. Select this option and enter an activation code if you have purchased a license for the application.

  If you specify an activation code for Kaspersky Anti-Virus or Kaspersky Total Security in the entry field, the procedure for switching to Kaspersky Anti-Virus or Kaspersky Total Security starts after activation is completed.

• Activate trial version of the application. Select this activation option if you want to install the trial version of the application before making a decision on whether to purchase a license. You will be able to use the application and all of its features during a short evaluation period. When the trial license expires, the trial version of the application cannot be activated for a second time.

An Internet connection is required for activation of the application.

During installation and activation of the application, you may be prompted to create a My Kaspersky account. We recommend that you connect the application to My Kaspersky so that you can save the activation code for subsequent recovery after reinstalling the operating system, installing protection to a new device, or reinstalling the application.

Registering and connecting to My Kaspersky

This step is not available in all versions of Kaspersky Internet Security.

Users registered on My Kaspersky are able to send requests to Technical Support and the Virus Lab, manage activation codes conveniently, and receive the latest information about new applications and special offers from Kaspersky.

• If you already have a My Kaspersky account, the Connect to My Kaspersky window opens. Enter your credentials for connecting the application to My Kaspersky portal and click the Sign in button.
• If you do not have a My Kaspersky account yet, the My Kaspersky account registration window opens. Fill out the registration form and click the Create button.

In some regions, the application prompts you to read and accept the regulation on data provisioning. If you accept the terms of the statement, click the Accept and connect button.

In some cases, registration on My Kaspersky is required to start using the application.

Completing activation

The Wizard informs you that Kaspersky Internet Security has been successfully activated.

Click the Done button to exit the Wizard.

Installing the application from the command prompt

You can install Kaspersky Internet Security from the command prompt.

Certain commands can be executed only under the administrator account.

Command prompt syntax:

<path to the file of the installation package> [parameters]

Detailed instructions and a list of installation settings are available on the Technical Support website.

Getting started

In order for Kaspersky Internet Security to fully support browsers, the Kaspersky Protection extension has to be installed and enabled in browsers. Kaspersky Internet Security uses the Kaspersky Protection extension to embed a script into the web page opened in Protected Browser and into traffic. The application uses this script to interact with the web page and to transmit data to banks whose websites are protected by the Safe Money component. The application protects data transmitted by the script using a digital signature. Kaspersky Internet Security can embed the script without using the Kaspersky Protection extension.

Kaspersky Internet Security signs data transmitted by the script using the installed anti-virus databases and requests to Kaspersky Security Network. The application sends requests to Kaspersky Security Network regardless of whether or not you accepted the terms of the Kaspersky Security Network Statement.

Installing the Kaspersky Protection extension in Chromium-based Microsoft Edge, Mozilla Firefox, and Google Chrome

The Kaspersky Protection extension is not automatically installed in Chromium-based Microsoft Edge, Mozilla Firefox, and Google Chrome. If the Kaspersky Protection extension is not installed in the browser, the application prompts you to go to the extensions download page and manually install Kaspersky Protection when the browser is started.

Yandex Browser support

When using Yandex Browser, the following application components are operating:

• Protected Browser
• URL Advisor
• Web Anti-Virus
• Anti-Phishing

The Private Browsing and Anti-Banner components operate but cannot be configured in Yandex Browser.

Internet Explorer support

Starting with Kaspersky Internet Security 2021, the Kaspersky Protection extension will no longer support the browser Internet Explorer. If you want to continue using the Kaspersky Protection extension in Internet Explorer, you can go back to the previous version of the application.

How to upgrade the application

The application is updated automatically if you select run mode Automatically in the update settings window (Database Update → Run mode).

The application is automatically updated if you install a new version of the application over the previous one.

If you have a current license for an earlier version of Kaspersky Internet Security, you do not need to activate the application. The Setup and Removal Wizard will automatically retrieve information about the license for the previous version of Kaspersky Internet Security and apply it during installation of the new version of Kaspersky Internet Security.

While downloading the update, the application compares the previous and new versions of the End User License Agreement, Kaspersky Security Network Statement, and Statement regarding data processing for marketing purposes. If the agreements and/or statements differ, the application offers you to read and accept them again.

The application can be upgraded if the following versions of Kaspersky Internet Security are installed on your computer:

• Kaspersky Internet Security 2015
• Kaspersky Internet Security 2016
• Kaspersky Internet Security 2017
• Kaspersky Internet Security 2018

• After an upgrade from a previous version, Kaspersky Internet Security starts automatically even if automatic startup of the application is disabled in the settings that have been saved. When the operating system restarts afterwards, Kaspersky Internet Security does not start automatically if automatic startup of the application is disabled in the settings that have been saved.

Installing over other Kaspersky applications

Installing a new version of Kaspersky Internet Security over a previous version of Kaspersky Anti-Virus

If you install a new version of Kaspersky Internet Security on a computer on which a previous version of Kaspersky Anti-Virus has been already installed with a current license, the Activation Wizard prompts you to select one of the following options:

• Continue using Kaspersky Anti-Virus under the current license. In this case, the Migration Wizard will be started. When the Migration Wizard finishes, the new version of Kaspersky Anti-Virus will be installed to your computer. You can use Kaspersky Anti-Virus until the license for the previous version of Kaspersky Anti-Virus expires.
• Proceed with installation of the new version of Kaspersky Internet Security. In this case, the application is installed and activated according to the standard scenario.

How to uninstall the application

After removing Kaspersky Internet Security, your computer and personal data will be unprotected.

Kaspersky Internet Security is removed using the Setup and Removal Wizard.

How to uninstall the application in Windows 7

How to uninstall the application in Windows 8 or later

Entering the password to remove the application

To remove Kaspersky Internet Security, you must enter the password for accessing the application settings. If you cannot specify the password, for any reason, application removal will be prohibited.

This step is displayed only if a password has been set for application removal.

Saving your activation code

Make sure that your activation code for Kaspersky Internet Security is saved on My Kaspersky. If you install Kaspersky Internet Security on another computer, you'll need the activation code.

If Kaspersky Internet Security is not connected to My Kaspersky, the Wizard prompts you to sign in to My Kaspersky, and then it saves the activation code in My Kaspersky.

Saving data for future use

During this step you can specify which of the data used by the application you want to keep for further use during the next installation of the application (for example, when installing a newer version of the application).

You can save the following data:

• License information is a set of data that rules out the need to activate the application during future installation, by allowing you to use it under the current license unless the license expires before you start the installation.
• Quarantine files are files scanned by the application and moved to Quarantine.

  After Kaspersky Internet Security is removed from the computer, quarantined files become unavailable. To perform operations with these files, Kaspersky Internet Security must be installed.

• Operational settings of the application are the values of the application settings selected during configuration.

  You can also export the protection settings at the command prompt, by using the following command: avp.com EXPORT <file_name>.

• iChecker data are files that contain information about objects that have already been scanned using
  iChecker technology

  iChecker is a technology that increases the speed of anti-virus scans by excluding objects that have remained unchanged since their last scan, provided that the scan parameters (the anti-virus database and settings) have not changed. The information for each file is stored in a special database. This technology is used in both real-time protection and on-demand scan modes.

  For example, you have an archive file that was scanned by a Kaspersky application and assigned not infected status. Next time, the application will skip this archive unless the archive has been altered or the scan settings have been changed. If you altered the archive content by adding a new object to it, modified the scan settings, or updated the anti-virus database, the archive is re-scanned.

  Limitations of iChecker technology:

  • This technology does not work with large files, since it is faster to scan a file than to check whether the file has been modified since it was last scanned.
  • The technology supports a limited number of formats (EXE, DLL, LNK, TTF, INF, SYS, COM, CHM, ZIP, RAR).
  .
• Anti-Spam databases are databases with specimens of spam messages added by the user.

Confirming application removal

Since removing the application threatens the security of your computer and personal data, you will be asked to confirm your intention to remove the application. To do this, click the Remove button.

Completing removal

During this step, the Wizard removes the application from your computer. Wait until removal is complete.

After you remove Kaspersky Internet Security, you can specify the reason why you decided to remove the application by leaving a comment on the Kaspersky website. To do this, visit the Kaspersky website by clicking the Complete form button.

This functionality may be unavailable in some regions.

During removal of the application, you must restart your operating system. If you cancel an immediate restart, completion of the removal procedure is postponed until the operating system is restarted or the computer is turned off and then started up.

Application licensing

This section covers the main aspects of application licensing.

About the End User License Agreement

The End User License Agreement is a binding agreement between you and AO Kaspersky Lab, stipulating the terms on which you may use the application.

Read through the terms of the License Agreement carefully before you start using the application.

You accept the terms of the License Agreement by confirming that you agree with the License Agreement when installing the application. If you do not accept the terms of the License Agreement, you must abort application installation and must not use the application.

About the license

A license is a time-limited right to use the application, granted under the End User License Agreement. The license is related to the unique code that you have for activating your copy of Kaspersky Internet Security.

A license entitles you to the following kinds of services:

• The right to use the application on one or several devices

  The number of devices on which you may use the application is specified in the End User License Agreement.

• Assistance from Kaspersky Technical Support
• Other services available from Kaspersky or its partners during the term of the license

To operate the application, you must purchase a license for application use.

The license has a limited term. License expiration may be followed by a grace period during which you may use all application features without limitations.

If you have not renewed your license, the application may switch to limited functionality mode when the grace period expires. Some application features are unavailable in limited functionality mode. The duration of limited functionality mode depends on your region and licensing terms. When limited functionality mode expires, all application features become unavailable. You may find information about the grace period and limited functionality mode in the Licensing window, which opens by clicking the License link in the lower part of the main window.

We recommend renewing the license before it expires, in order to ensure maximum protection of your computer against all security threats.

Before purchasing a license, you can get a free trial version of Kaspersky Internet Security. The trial version of Kaspersky Internet Security remains functional during a short evaluation period. After the evaluation period expires, all the features of Kaspersky Internet Security are disabled. To continue using the application, you must purchase a license.

If you do not wish to renew protection of your computer, you can remove Kaspersky Internet Security.

About limited functionality mode

The table below shows which Kaspersky Internet Security features are available and which are unavailable when the application is in limited functionality mode. If the value in the Limited functionality mode column is "yes", this means that the relevant functionality is available in limited functionality mode. If the value in the Limited functionality mode column is "no", the relevant functionality is unavailable. Additional information is available in the Restrictions column.

About the activation code

An activation code is a code that you receive when you purchase a license for Kaspersky Internet Security. This code is required for activation of the application.

The activation code is a unique sequence of twenty digits and Latin letters in the format xxxxx-xxxxx-xxxxx-xxxxx.

Depending on how you purchased the application, you can obtain the activation code in one of the following ways:

• When you purchase a boxed version of Kaspersky Internet Security, an activation code is provided in the manual or on the retail box that contains the installation CD.
• When you purchase Kaspersky Internet Security from an online store, an activation code is emailed to the address that you have specified when ordering.

The license term countdown starts from the date when you activate the application. If you have purchased a license for the use of Kaspersky Internet Security on several devices, the license term starts counting down from the moment you first apply the activation code.

We recommend that you create a My Kaspersky account so that you do not lose your activation code when you reinstall your operating system, install the application on a new device or reinstall the application on your current device. You can create a My Kaspersky account at the time of application installation and activation. If you didn't create a My Kaspersky account at the time of application installation and activation, you can also create an account in the installed application.

If you delete your activation code by mistake or lose it, you can try to restore it.

How to restore activation codes

If you have lost an activation code that was previously provided to you, you can restore it using one of the following methods:

• If you have a My Kaspersky account, you can find your activation codes in the Licenses section of the My Kaspersky website.
• If you have no My Kaspersky account, but the application is installed and activated on one of your devices, create a My Kaspersky account on this device and use it to connect to My Kaspersky. The application will transmit information about your license to the account. The activation code will be displayed in the Licenses section of the My Kaspersky website.
• If you have neither a My Kaspersky account nor an activated application on any of your devices, then please contact Technical Support.

You can read more about how to restore activation codes using My Kaspersky.

About the subscription

A subscription to Kaspersky Internet Security establishes use of the application within the selected settings (expiration date and number of protected devices). You can obtain a subscription for Kaspersky Internet Security from a service provider (for example, from your Internet provider). You can pause or resume your subscription, renew it automatically, or cancel it. You can manage your subscription via your personal account page on the service provider's website.

Vendors can provide two types of subscriptions for Kaspersky Internet Security: update subscriptions and update and protection subscriptions.

A subscription can be limited (for example, to one year) or unlimited (with no expiration date). To continue using Kaspersky Internet Security after a limited subscription expires, you must renew it. Unlimited subscriptions are renewed automatically as long as timely prepayment has been made to the service provider.

When a limited subscription expires, you are given a grace period to renew your subscription. Application functionality remains unchanged during this time.

If the subscription is not renewed before the grace period expires, Kaspersky Internet Security stops updating the application databases (in the case of update subscriptions), stops interacting with Kaspersky Security Network, and also stops protecting the computer and running scan tasks (in the case of update and protection subscriptions).

To use Kaspersky Internet Security by subscription, apply the activation code received from your service provider. In some cases, an activation code can be downloaded and applied automatically. When using the application by subscription, you cannot apply another activation code to renew your license. You can apply another activation code only when the subscription term expires.

If Kaspersky Internet Security is already in use under a current license when you register your subscription, after registration Kaspersky Internet Security will be used by subscription. The activation code that you have used to activate the application can be applied on another computer.

To cancel your subscription, contact the service provider from whom you have purchased Kaspersky Internet Security.

Depending on the subscription provider, the set of subscription management options may vary. In addition, you may not be provided with a grace period during which you can renew the subscription.

5. Click the Done button.

The new activation code will be displayed in the Licensing window.

The application is automatically activated with the new activation code when the license expires. You can also activate the application manually with a new activation code, by clicking the Activate now button. This button is available if the application has not been activated automatically. This button is unavailable before the license expires.

If the new activation code that you specify has already been applied on this computer or on another computer, the activation date for the purpose of renewing the license is the date on which the application was first activated with this activation code.

When you renew the current license, the activation code does not change. The license will be automatically renewed in the application after purchase. You do not need to re-enter the activation code in the application.

It can take up to 24 hours after purchase before the correct license status is displayed.

• Critical notifications inform you of events that have critical importance for the computer's security, such as detection of a malicious object or dangerous activity in the operating system. Windows used for critical notifications and pop-up messages are red.
• Important notifications inform you of events that are potentially important for the computer's security, such as detection of a probably infected object or suspicious activity in the operating system. Windows used for important notifications and pop-up messages are yellow.
• Information notifications inform you of events that do not have critical importance for the computer's security. Windows used for information notifications and pop-up messages are green.

If a notification is displayed on the screen, you should select one of the options that are suggested in the notification. The optimal option is the one recommended as the default by Kaspersky experts.

A notification can be closed automatically when the computer is restarted, when Kaspersky Internet Security is quit, or in Connected Standby mode in Windows 8. Application Control notifications are closed automatically after 500 seconds. Notifications about the startup of applications are closed after 1 hour. When a notification is closed automatically, Kaspersky Internet Security performs the default recommended action.

Notifications are not displayed during the first hour of application operation if you have purchased a computer with Kaspersky Internet Security preinstalled (OEM distribution). The application processes detected objects in accordance with the recommended actions. The results of this processing are saved in a report.

Update databases and application modules

This section contains information about database and application module updates.

About database and application module updates

The installation package of Kaspersky Internet Security includes databases and application modules. Using these databases:

• Kaspersky Internet Security detects the majority of threats using Kaspersky Security Network, which requires an Internet connection.
• Kaspersky Internet Security detects adware, auto dialers, and other legitimate software that can be used by intruders to damage your computer or personal data.

To get full protection, we recommend updating the databases and application modules as soon as the application has been installed.

Databases and program modules are updated in stages:

1. Kaspersky Internet Security starts updating databases and application modules according to the specified settings: automatically, on schedule, or on demand. The application contacts an update source that stores a database and application module update package.
2. Kaspersky Internet Security compares the existing databases with the databases available at the update source. If the databases are different, Kaspersky Internet Security downloads the missing parts of the databases.

The application then uses the updated databases and application modules to scan the computer for viruses and other threats.

Update sources

You can use the following update sources:

• Kaspersky update servers
• HTTP or FTP server
• Network folder

Special considerations when updating databases and application modules

Updates of databases and application modules are subject to the following restrictions and specifics:

• Databases are considered out of date after one day and extremely out of date after seven days.
• To download an update package from Kaspersky servers, an Internet connection is required.
• Updates of databases and application modules are unavailable in the following cases:
  • The license has expired, and the grace period or limited functionality mode is not available.
  • A metered mobile Internet connection is used. This limitation applies on computers running under Microsoft Windows 8 or more recent versions of this operating system if automatic updates or scheduled updates are enabled and a traffic limit has been set for a metered mobile connection. If you want the application to update databases and application modules in this case, clear the Limit traffic on metered connections check box under Settings → Network settings.
  • The application is used under subscription, and you have suspended your subscription on the website of the service provider.

Installing an update package

When an update package (patch) is received, Kaspersky Internet Security installs it automatically. To complete the installation of an update package, you must restart the computer. Until the computer is restarted, the application icon in the notification area is red, and the Kaspersky Internet Security Notification Center window displays a prompt to restart the computer.

How to recover the operating system after infection

This section contains information on restoring the operating system after it has been infected with malware.

Recovering the operating system after infection

If you suspect that the operating system of your computer has been corrupted or modified due to malware activity or a system failure, use the Microsoft Windows Troubleshooting Wizard, which clears the system of any traces of malicious objects. Kaspersky recommends that you run the Wizard after the computer has been disinfected to make sure that all threats and damage caused by infections have been fixed.

The Wizard checks whether there are any changes to the system, which can include access to the network being blocked, file name extensions for known formats being changed, Control Panel being blocked, etc. There are different reasons for these different kinds of damage. These reasons may include malware activity, incorrect system configuration, system failures, or malfunctioning applications for system optimization.

After the review is complete, the Wizard analyzes the information to evaluate whether there is system damage that requires immediate attention. Based on the review, the Wizard generates a list of actions that are necessary to eliminate the damage. The Wizard groups these actions by category based on the severity of the problems detected.

Troubleshooting the operating system by using the Microsoft Windows Troubleshooting Wizard

To run the Microsoft Windows Troubleshooting Wizard:

1. Open the main application window.
2. In the lower part of the main window, click the More Tools button.

More details on using Kaspersky Rescue Disk are available on the Technical Support website.

Protecting email

This section provides information about how to protect your email against spam, viruses, and other threats.

Configuring Mail Anti-Virus

Kaspersky Internet Security allows scanning email messages for dangerous objects by using Mail Anti-Virus. Mail Anti-Virus starts when the operating system is started and remains constantly in the RAM of the computer, scanning all email messages that are sent or received over the POP3, SMTP, IMAP, and NNTP protocols, as well as via encrypted connections (SSL) over the POP3, SMTP, and IMAP protocols.

By default, Mail Anti-Virus scans both incoming and outgoing messages. If necessary, you can enable scanning of incoming messages only.

To configure Mail Anti-Virus:

1. Open the main application window.
2. Click the button in the lower part of the window.

   The Settings window opens.

3. In the Protection section, select the Mail Anti-Virus component.

   The Mail Anti-Virus settings are displayed in the window.

4. Make sure that the switch in the upper part of the window that enables / disables Mail Anti-Virus, is enabled.
5. Select a security level:
   • Recommended. When this security level is set, Mail Anti-Virus scans incoming and outgoing messages and attached archives, and performs heuristic analysis with the Medium scan level of detail.
   • Low. If you select this security level, Mail Anti-Virus scans incoming messages only, without scanning attached archives.
   • High. When this security level is set, Mail Anti-Virus scans incoming and outgoing messages and attached archives, and performs heuristic analysis with the Deep scan level of detail.
6. In the Action on threat detection section, select the action that you want Mail Anti-Virus to perform when an infected object is detected (for example, disinfect).

If no threats are detected in an email message, or if all infected objects have been successfully disinfected, the message becomes available for further access. If the component fails to disinfect an infected object, Mail Anti-Virus renames or deletes the object from the message and adds a notification to the message subject line, stating that the message has been processed by Kaspersky Internet Security. Before deleting an object, Kaspersky Internet Security creates a backup copy of it and places a copy in Quarantine.

When you upgrade to a more recent application version, the user-configured Mail Anti-Virus settings are not saved. The new application version will use the default Mail Anti-Virus settings.

If Kaspersky Internet Security detects the password for the archive in the message text during scanning, the password is used to scan the contents of that archive for malware. The password is not saved. The archive is unpacked before scanning. If the application crashes while unpacking the archive, you can manually delete the files that are unpacked at the following path: %systemroot%\temp. The files have the PR prefix.

Blocking unwanted email (spam)

If you receive large amounts of unwanted messages (spam), we recommend that you enable the Anti-Spam component and set the Recommended security level for it.

To enable Anti-Spam and set the Recommended security level:

1. Open the main application window.
2. Click the button in the lower part of the window.

   The Settings window opens.

3. Select the Protection section.
4. Select the Anti-Spam component.

   The window displays the settings of Anti-Spam.

5. Enable Anti-Spam using the switch.
6. In the Security level section, make sure that the Recommended security level is set.

The following limitations apply to Anti-Spam:

• The Anti-Spam component can only analyze messages that are fully downloaded from the mail server, regardless of the protocol used.
• The Anti-Spam component does not check mail transferred using MAPI protocol.

The Anti-Spam component is disabled when you upgrade to a more recent application version. You can enable the component manually.

In some application versions, to enable the Anti-Spam component, you must accept the terms of the Statement regarding data processing for Anti-Spam.

About On-Screen Keyboard

When using the Internet, you frequently need to enter your personal data or your user name and password. This happens, for example, during account registration on websites, online shopping, and Internet banking.

There is a risk that personal data can be intercepted by hardware keyboard interceptors or keyloggers, which are programs that record keystrokes. The On-Screen Keyboard tool prevents the interception of data entered via the keyboard.

Many programs classified as spyware can take screenshots, which then are automatically transmitted to an intruder for further analysis to steal the user's personal data. On-Screen Keyboard protects entered personal data from attempts to intercept it by means of screenshots.

On-Screen Keyboard has the following features:

• You can click the On-Screen Keyboard buttons with the mouse.
• Unlike hardware keyboards, it is impossible to press several keys simultaneously on On-Screen Keyboard. This is why key combinations (such as ALT+F4) require that you click the first key (for example, ALT), then the second key (for example, F4), and then the first key again. The second click of the key acts in the same way as releasing the key on a hardware keyboard.
• The On-Screen Keyboard language can be switched by using the same shortcut that is specified by the operating system settings for the hardware keyboard. To do so, right-click the other key (for example, if the LEFT ALT+SHIFT shortcut is configured in the operating system settings for switching the keyboard language, left-click the LEFT ALT key and then right-click the SHIFT key).

To ensure protection of data entered via On-Screen Keyboard, restart your computer after installing Kaspersky Internet Security.

The use of On-Screen Keyboard has the following limitations:

• On-Screen Keyboard prevents interception of personal data only when used with the Chromium-based Microsoft Edge, Mozilla Firefox, or Google Chrome browsers. When used with other browsers, On-Screen Keyboard does not protect entered personal data against interception.
• On-Screen Keyboard cannot protect your personal data if the website requiring the entry of such data is hacked, because in this case the information is obtained directly by the intruders from the website.
• On-Screen Keyboard does not prevent screenshots that are made by using the Print Screen key and other combinations of keys specified in the operating system settings.

Kaspersky Internet Security does not provide protection against unauthorized screenshots in Microsoft Windows 8 and 8.1 (64-bit only) if the On-Screen Keyboard window is open but the Protected Browser process is not started.

The preceding list describes the main restrictions in functionality for protection of data input. A full list of restrictions is given in an article on the Kaspersky Technical Support website.

About secure connection to Wi-Fi networks

Public Wi-Fi networks may be under-protected, for example, if a Wi-Fi network uses a vulnerable encryption protocol or a weak password. When you make Internet purchases over an insecure Wi-Fi network, your passwords and other confidential data are transmitted in non-encrypted text. Hackers can intercept your confidential data, find out your bank card number, and obtain access to your money.

When connecting to a Wi-Fi network, the application checks this network. If the Wi-Fi network is not secure, the application prompts you to enable a secure connection via a specially allocated server located in the region you specify. The website data is first transferred to the allocated server. The application then sends the data to your device over an encrypted secure connection.

To use the Kaspersky VPN component, you need to run the Kaspersky VPN Secure Connection application. Kaspersky VPN Secure Connection application is installed together with Kaspersky Internet Security.

The Kaspersky VPN component provides the following advantages:

• Safe use of payment systems and booking sites. Intruders will not be able to intercept the number of your bank card when you make online payments, book hotel rooms, or rent cars.
• Protection of your secret information. No one will be able to determine the IP address of your computer or your location.
• Protection of your privacy. No one will be able to intercept and read your private correspondence on social networks.

Kaspersky VPN can also be used for other types of network connections such as a local Internet connection or USB modem connection.

By default, Kaspersky VPN Secure Connection does not prompt you to enable VPN if the HTTPS protocol is used to connect to a website.

Changing the virtual location when visiting websites of banks, payment systems, booking websites, social networks, chats, and email websites could result in the triggering of anti-fraud systems (systems intended for analyzing online financial transactions for signs of fraudulent operations).

Use of Kaspersky VPN may be regulated by local legislation. You may use Kaspersky VPN only in accordance with its purpose and without violating local legislation.

How to run Kaspersky VPN Secure Connection

Kaspersky VPN Secure Connection is installed together with Kaspersky Internet Security. You can start Kaspersky VPN Secure Connection from the Start menu (in the Microsoft Windows 7 operating system or earlier version), from the start screen (in the Microsoft Windows 8 operating system or later versions), or from the window of Kaspersky Internet Security.

To start Kaspersky VPN Secure Connection from the Kaspersky Internet Security window:

1. Open the main application window.
2. In the lower part of the main window, click the More Tools button.

   The Tools window opens.

3. Go to the My Network section.
4. Click the Kaspersky VPN link to open the Kaspersky VPN window.
5. Click the Open button.

This opens the main application window of Kaspersky VPN Secure Connection.

More details about the operation of Kaspersky VPN Secure Connection are available in the help files of this application.

Configuring notifications of vulnerabilities in Wi-Fi networks

If Kaspersky VPN Secure Connection is not installed on your computer, Kaspersky Internet Security displays a notification about the insecure transmission of your password over the Internet. You can allow or block password transmission in the notification window.

After you have installed Kaspersky VPN Secure Connection, the settings for the display of notifications when connecting to Wi-Fi networks and transmitting an unencrypted password become inactive. You can configure the notification settings for Wi-Fi network connections in Kaspersky VPN Secure Connection.

To configure notifications of vulnerabilities on Wi-Fi networks:

1. Open the main application window.
2. Click the button in the lower part of the window.

   The Settings window opens.

3. Select the Protection section.
4. Select the Firewall component.

   The window displays the settings of the Firewall component.

5. Select the Notify of vulnerabilities in Wi-Fi networks if you want to receive notifications when you are connecting to vulnerable Wi-Fi networks. If you do not want to receive notifications, clear the check box. This check box can be accessed if Kaspersky VPN Secure Connection is not installed on the computer.
6. If the Notify of vulnerabilities in Wi-Fi networks check box is selected, you can edit the advanced settings for display of notifications:
   • Select the Block and warn about insecure transmission of passwords over the Internet check box to block all transmission of passwords in non-encrypted text format when you fill in the Password fields on the Internet.
   • Click the Reset hidden alerts link to roll back to the default values of settings for display of notifications about transfers of passwords in non-encrypted form. If you have previously blocked display of notifications about password transfer in non-encrypted form, display of these notifications will resume.

Protecting financial transactions and online purchases

This section provides instructions on how you can protect your financial transactions and purchases online with Kaspersky Internet Security.

About protection of financial transactions and online purchases

To protect confidential data that you enter on websites of banks and payment systems (such as bank card numbers and passwords for online banking), as well as to prevent funds from being stolen when you make online payments, Kaspersky Internet Security prompts you to open such websites in Protected Browser.

Protected Browser is a special browser operating mode designed to protect your data as you access bank or payment system websites. Protected Browser is started in an isolated environment to prevent other applications from injecting their code into the process of Protected Browser. Kaspersky Internet Security creates special profiles for the Mozilla Firefox and Google Chrome browsers to prevent third-party add-ons from affecting the operation of Protected Browser. The application does not affect your data that the browsers may save in the profiles created for them.

If you are using Chromium-based Microsoft Edge, Google Chrome, Mozilla Firefox, or Internet Explorer, Protected Browser is opened in a new window.

The application uses the Kaspersky Protection extension to provide a number of Protected Browser functions.

Browsers that do not meet the software requirements cannot operate in Protected Browser mode. Instead of such browsers, either Chromium-based Microsoft Edge or another browser configured in application settings starts in Protected Browser mode.

It is impossible to run Protected Browser under the following conditions:

• check box is cleared in the Enable Self-Defense subsection of the General section of the application settings window;
• Javascript is disabled in the browser.

Running Protected Browser in Yandex Browser

Kaspersky Internet Security supports securing your financial transactions in Yandex Browser with some limitations. To run Protected Browser, the application injects a special script into the web page (and traffic). The Kaspersky Protection extension is not available. The Private Browsing and Anti-Banner components operate but cannot be configured in Yandex Browser.

Protected Browser capabilities

In Protected Browser mode, the application provides protection against the following types of threats:

• Untrusted modules. The application runs a check for untrusted modules every time you visit a bank or payment system website.
• Rootkits. The application scans for rootkits at Protected Browser startup.
• Invalid certificates of bank or payment system websites. The application checks certificates when you visit a bank or payment system website. The check is performed against a database of compromised certificates.

Protected Browser status

When you open a website in Protected Browser, a frame appears on the borders of the browser window. The color of the frame indicates the protection status.

The frame of the browser window can display the following color indications:

• Green frame. Signifies that all checks have been performed successfully. You can continue using Protected Browser.
• Yellow frame. Signifies that checks have revealed security problems that need to be resolved.

  The application can detect the following threats and security problems:

  • Untrusted module. Computer scanning and disinfection is required.
  • Rootkit. Computer scanning and disinfection is required.
  • Invalid certificate of a bank or payment system website.

  If you do not eliminate the threats detected, the security of the bank or payment system website connection session is not guaranteed. Events involving the launch and use of Protected Browser with reduced protection are recorded in the Windows event log.

About protection against screenshots

To protect your data when you browse protected websites, Kaspersky Internet Security prevents spyware from taking unauthorized screenshots. Protection against screenshots is enabled by default. Protection against screenshots is running even if hardware virtualization is disabled.

About clipboard data protection

Kaspersky Internet Security blocks unauthorized access by applications to the clipboard when you make online payments, thus preventing theft of data by criminals. Such blocking is active only if an untrusted application attempts to obtain unauthorized access to your clipboard. If you copy data manually from the window of an application to another application's window (for example, from Notepad to a text editor window), access to clipboard is allowed.

Clipboard protection is not running if hardware virtualization is disabled on your computer.

If Protected Browser is started under the Microsoft Windows 10 operating system, Kaspersky Internet Security will block interaction of Universal Windows applications with the clipboard.

Webcam Protection

This section contains information about how to prevent people from spying on you via webcam.

About applications' access to the webcam

The Webcam Protection component is designed to protect your webcam against unauthorized access. If Webcam Protection is enabled and the Block access to webcam for all applications check box is selected, Kaspersky Internet Security blocks access to the webcam for all applications and notifies you that access has been blocked.

If the Block access to webcam for all applications check box is cleared, Kaspersky Internet Security monitors application access to the webcam depending on the trust group of the application that requests access. Kaspersky Internet Security blocks access to the webcam for applications that have been included in the High Restricted or Untrusted groups.

In the Application Control settings window, you can allow access to the webcam for applications included in the High Restricted and Untrusted groups. If an application from the Low Restricted trust group attempts to connect to the webcam, Kaspersky Internet Security displays a notification and prompts you to decide whether to provide that application with access to the webcam.

If a webcam access attempt is made by an application that is denied access by default, Kaspersky Internet Security shows a notification. The notification shows information to the effect that an application installed on the computer (such as Skype) is currently receiving video data from the webcam. In the notification drop-down list, you can block the application from accessing the webcam or proceed to configure the settings of application access to the webcam. This notification is not displayed if applications are already running in full-screen mode on your computer.

In the drop-down list of the notification about video data received by the application, you can also choose to hide notifications or proceed to configure notification display settings.

By default, Kaspersky Internet Security allows webcam access to applications that require your permission if the application's GUI is still being loaded, unloaded, or not responding, and you cannot allow access manually.

Webcam access protection functionality has the following features and limitations:

• The application controls video and still images derived from processing of webcam data.
• The application controls the audio signal if it is part of the video stream coming from the webcam.
• Kaspersky Internet Security controls only webcams connected via USB or IEEE1394 that are displayed in Windows Device Manager as Imaging Devices.

Click this link to view the list of supported webcams.

Handling unknown applications

Kaspersky Internet Security helps to minimize the risk associated with using unknown applications (such as the risk of infection with viruses and other malware).

Kaspersky Internet Security includes components and tools that allow checking an application's reputation and controlling its activities on your computer.

Checking application reputation

Kaspersky Internet Security allows you to verify the reputation of applications with users all over the world. The reputation of an application comprises the following criteria:

• Name of the vendor
• Information about the
  digital signature

  An encrypted block of data embedded in a document or application. A digital signature is used to identify the author of the document or application. To create a digital signature, the document or application author must have a digital certificate proving the author's identity.

  A digital signature lets you verify the data source and data integrity and protect yourself against counterfeits.

  (if the application is digitally signed)
• Information about the group to which the application has been assigned by Application Control or most users of Kaspersky Security Network
• Number of users of Kaspersky Security Network who use the application (available if the application has been included in the Trusted group in the Kaspersky Security Network database)
• Time at which the application become known to Kaspersky Security Network
• Countries in which the application is the most widespread

Checking of application reputation is available if you have agreed to participate in Kaspersky Security Network.

To learn the reputation of an application:

Open the context menu of the application's executable file and select Check reputation in KSN.

This opens a window with information about the reputation of the application in Kaspersky Security Network.

Controlling application activity on the computer and on the network

The Application Control component prevents applications from performing actions that may be dangerous for the operating system, and controls access to operating system resources (including file resources located on remote computers) and your personal data.

Application Control tracks actions performed in the operating system by applications installed on the computer and regulates them based on rules. These rules restrict suspicious activity of applications, including access by applications to protected resources, such as files and folders, registry keys, and network addresses.

On 64-bit operating systems, applications' rights for the following actions cannot be configured:

• Direct access to physical memory
• Managing printer driver
• Service creation
• Service reading
• Service editing
• Service reconfiguration
• Service management
• Service start
• Service removal
• Access to internal browser data
• Access to critical objects of the operating system
• Access to password storage
• Setting debug privileges
• Use of program interfaces of the operating system
• Use of program interfaces of the operating system (DNS)
• Use of program interfaces of other applications
• Change system modules (KnownDlls)
• Start drivers

On 64-bit Microsoft Windows 8 and Microsoft Windows 10, applications' rights for the following actions cannot be configured:

• Sending windows messages to other processes
• Suspicious operations
• Installation of keyloggers
• Interception of inbound stream events
• Making of screenshots

Applications' network activity is controlled by the Firewall component.

When an application is started on the computer for the first time, Application Control checks the safety of the application and assigns it to a group (Trusted, Untrusted, High Restricted, or Low Restricted). The group defines the rules that Kaspersky Internet Security applies for controlling the activity of the application.

Kaspersky Internet Security assigns applications to trust groups (Trusted, Untrusted, High Restricted, or Low Restricted) only if Application Control or Firewall is enabled, and also when both these components are enabled. If both these components are disabled, the functionality that assigns applications to trust groups does not work.

You can edit application control rules manually.

The rules you create for applications are inherited by child applications. For example, if you deny all network activity for cmd.exe, that activity will also be denied for notepad.exe when it is started using cmd.exe. When an application is not a child of the application it runs from, rules are not inherited.

Starting with Kaspersky Internet Security 2021, the Trusted Applications mode is no longer included with the application. If you want to continue using this component, you can go back to the previous version of the application.

About protecting an audio stream coming from sound recording devices

Intruders may attempt to receive the audio stream from sound recording devices by means of special software. Sound recording devices are microphones that are connected to or built into the computer and capable of transmitting an audio stream through the sound card interface (input signal). Kaspersky Internet Security monitors which applications receive an audio stream from sound recording devices and protects the audio stream from unauthorized intercepts.

By default, Kaspersky Internet Security blocks applications from Untrusted and High Restricted trust groups from receiving the audio stream coming from sound recording devices connected to the computer. You can manually allow applications to receive the audio stream from sound recording devices.

If an application from the Low Restricted trust group is requesting access to a sound recording device, Kaspersky Internet Security displays a notification and prompts you to choose whether or not to allow this application to receive the audio stream from a sound recording device. If Kaspersky Internet Security is unable to display this notification (for example, when the Kaspersky Internet Security graphical interface has not yet loaded), the application from the Low Restricted trust group is allowed to receive the audio stream from a sound recording device.

All applications in the Trusted group are allowed to receive an audio stream from sound recording devices by default.

Audio stream protection has the following special features:

• The Application Control component has to be enabled for this functionality to work.
• After the settings of application access to sound recording devices have been changed (for example, the application has been prohibited from receiving the audio stream in the Application Control settings window), this application has to be restarted to stop it from receiving the audio stream.
• Control of access to the audio stream from sound recording devices does not depend on an application's webcam access settings.
• Kaspersky Internet Security protects access to built-in microphones and external microphones only. Other audio streaming devices are not supported.
• Kaspersky Internet Security allows an application to receive an audio stream and does not show any notifications if the application began to receive the audio stream before Kaspersky Internet Security was started, or if you placed the application into the Untrusted or High Restricted group after the application began to receive the audio stream.

Kaspersky Internet Security does not guarantee protection of the audio stream from such devices as DSLR cameras, camcorders, and action cameras.

How to change audio stream protection settings

To change audio stream protection settings:

1. Open the main application window.
2. In the lower part of the main window, click the More Tools button.

How to pause and resume computer protection

Pausing protection means temporarily disabling all protection components for some time.

When protection is paused or Kaspersky Internet Security is not running, the activity of the applications running on your computer is monitored. Information about the results of monitoring of application activity is saved in the operating system. When Kaspersky Internet Security is started again or protection is resumed, the application uses this information to protect your computer from malicious actions that may have been performed when protection was paused or when Kaspersky Internet Security was not running. Information about the results of monitoring of application activity is stored indefinitely. This information is deleted if Kaspersky Internet Security is removed from your computer.

To pause the protection of your computer:

1. In the context menu of the application icon located in the taskbar notification area, select the Pause protection item.

   The Pause protection window opens (see the following figure).

Limitations and warnings

Kaspersky Internet Security has a number of limitations that are not critical to operation of the application.

Limitations on the operation of certain components and automatic processing of files

Infected files and malicious links are processed automatically according to rules created by Kaspersky specialists. You cannot modify these rules manually. Rules can be updated following an update of databases and application modules. The rules for Firewall, Webcam Protection, Application Manager, Software Cleaner, and Application Control are also updated automatically.

If a device scan is started from My Kaspersky, files will be processed automatically based on the rules specified in the application. Files detected on a device can be processed automatically by request from My Kaspersky without your confirmation.

Limitations on connection to Kaspersky Security Network

During its operation, the application may query Kaspersky Security Network for information. If data from Kaspersky Security Network could not be retrieved, the application makes decisions based on local anti-virus databases.

Limitations of System Watcher functionality

Protection against cryptors (malware that encrypts user files) has the following limitations:

• The Temp system folder is used to support this functionality. If the system drive with the Temp folder has insufficient disk space to create temporary files, protection against cryptors is not provided. In this case, the application does not display a notification that files are not backed up (protection is not provided).
• Temporary files are deleted automatically when you close Kaspersky Internet Security or disable the System Watcher component.
• In case of an emergency termination of Kaspersky Internet Security, temporary files are not deleted automatically. To delete temporary files, clear the Temp folder manually. To do so, open the Run window and in the Open field type %TEMP%. Click OK.
• Protection against encryptors is provided only for files that are located on data drives that have been formatted with the NTFS file system.
• The number of files that can be restored cannot exceed 50 per one encryption process.
• The total volume of modifications to files cannot exceed 100 MB. Files with modifications that exceed this limit cannot be restored.
• File modifications initiated via network interface are not monitored.
• Files encrypted with EFS are not supported.
• You must restart the computer to enable protection against encryptors after Kaspersky Internet Security is installed.

Encrypted connections scan limitations

Due to technical limitations of the implementation of scanning algorithms, scanning of encrypted connections does not support certain extensions of the TLS 1.0 protocol and later versions (particularly NPN and ALPN). Connections via these protocols may be limited. Browsers with SPDY protocol support use the HTTP over TLS protocol instead of SPDY even if the server to which the connection is established supports SPDY. This does not affect the level of connection security. If the server supports only the SPDY protocol and it is impossible to establish the connection via the HTTPS protocol, the application does not monitor the connection established.

Kaspersky Internet Security does not support processing of HTTPS/2 Proxy traffic. The application does not process traffic transmitted via extensions of the HTTP/2 protocol.

Kaspersky Internet Security prevents data exchange over the QUIC protocol. Browsers use a standard transport protocol (TLS or SSL) regardless of whether or not support for the QUIC protocol is enabled in the browser.

Kaspersky Internet Security monitors only those protected connection which it is able to decrypt. The application does not monitor connections added to the list of exclusions (Websites link in the Network settings window).

The following components perform decryption and scanning of encrypted traffic by default:

• Web Anti-Virus
• Safe Money
• URL Advisor
• Parental Control

Kaspersky Internet Security decrypts encrypted traffic while the user is using the Google Chrome browser if the Kaspersky Protection extension is disabled in this browser.

Kaspersky Internet Security does not monitor traffic if the browser loads a web page or its elements from a local cache instead of from the Internet.

Limitations on encrypted connections scan exclusions

When scanning encrypted connections with websites that have been added to exclusions, certain components such as Anti-Banner, URL Advisor and Private Browsing may continue to scan encrypted connections. The Safe Money, Parental Control and Web Anti-Virus components do not scan websites that have been added to exclusions.

Specifics of kernel memory scanning for rootkits in Protected Browser mode

When an untrusted module is detected in Protected Browser mode, a new browser tab opens with a notification about malware detection. If this happens, you are recommended to exit the browser and run a Full Scan of the computer.

Specifics of clipboard data protection

Kaspersky Internet Security allows an application to access clipboard in the following cases:

• An application with the active window attempts to place data in clipboard. The active window is the window that you are currently using.
• A trusted process of an application attempts to place data in clipboard.
• A trusted process of an application or a process with the active window attempts to receive data from clipboard.
• An application process that previously placed data in clipboard attempts to receive this data from clipboard.

Specifics of infected file processing by application components

By default, the application can delete infected files that cannot be disinfected. Removal by default can be performed during file processing by such components as Application Control, Mail Anti-Virus, File Anti-Virus, during scan tasks, and also when System Watcher detects malicious activity of applications.

Limitations applicable to certain components in case of application installation together with Kaspersky Fraud Prevention for Endpoints

Operation of the following Kaspersky Internet Security components is limited in Protected Browser if the application is installed together with Kaspersky Fraud Prevention for Endpoints:

• Web Anti-Virus, except Anti-Phishing
• Parental Control

If UMCI mode is enabled in Windows, Kaspersky Internet Security does not detect screen lockers.

About logging of events in the Windows event log that are related to the End User License Agreement and Kaspersky Security Network

Events involving accepting and declining the terms of the End User License Agreement, and also accepting and declining participation in Kaspersky Security Network, are recorded in the Windows event log.

Limitations on local address reputation checks in Kaspersky Security Network

Links to local resources are not scanned in Kaspersky Security Network.

Warning about applications that collect information

If an application that collects information and sends it to be processed is installed on your computer, Kaspersky Internet Security may classify this application as malware. To avoid this, you can exclude the application from scanning by configuring Kaspersky Internet Security as described in this document.

Warning about the creation of an application installation report

In the Community, you can view existing topics, leave your comments, and create new discussion topics.

Glossary

Activating the application

Switching the application to fully functional mode. Application activation is performed by the user during or after installation of the application. To activate the application, the user must have an activation code.

Activation code

A code that you receive when purchasing a license for Kaspersky Internet Security. This code is required for activation of the application.

The activation code is a unique sequence of twenty alphanumeric characters in the format xxxxx-xxxxx-xxxxx-xxxxx.

Anti-virus databases

Databases that contain information about computer security threats known to Kaspersky as of when the anti-virus databases are released. Entries in anti-virus databases allow detecting malicious code in scanned objects. Anti-virus databases are created by Kaspersky specialists and updated hourly.

Application modules

Files included in the Kaspersky installation package that are responsible for performing the main tasks of the corresponding application. A particular application module corresponds to each type of task performed by the application (protection, scan, updates of databases and application modules).

Blocking an object

Denying access to an object from third-party applications. A blocked object cannot be read, executed, modified, or deleted.

Compressed file

A compressed executable file that contains a decompression program and instructions for the operating system to execute it.

Database of malicious web addresses

A list of web addresses whose content may be considered to be dangerous. Created by Kaspersky specialists, the list is regularly updated and is included in the Kaspersky application package.

Database of phishing web addresses

List of web addresses which have been defined as phishing web addresses by Kaspersky specialists. The databases are regularly updated and are part of the Kaspersky application package.

Digital signature

An encrypted block of data embedded in a document or application. A digital signature is used to identify the author of the document or application. To create a digital signature, the document or application author must have a digital certificate proving the author's identity.

A digital signature lets you verify the data source and data integrity and protect yourself against counterfeits.

Disk boot sector

A boot sector is a special area on a computer's hard drive, floppy disk, or other data storage device. It contains information on the disk's file system and a boot loader program, which is responsible for starting the operating system.

There exist a number of viruses that infect boot sectors, which are thus called boot viruses. The Kaspersky application allows scanning boot sectors for viruses and disinfecting them if an infection is found.

Exploit

A software code that uses a vulnerability in the system or software. Exploits are often used to install malware on the computer without user's knowledge.

False positive

A situation when a Kaspersky application considers a non-infected object to be infected because the object's code is similar to that of a virus.

File mask

Representation of a file name using wildcards. The standard wildcards used in file masks are * and ?, where * represents any number of any characters and ? stands for any single character.

Heuristic analyzer

A technology for detecting threats about which information has not yet been added to Kaspersky databases. The heuristic analyzer detects objects whose behavior in the operating system may pose a security threat. Objects detected by the heuristic analyzer are considered to be probably infected. For example, an object may be considered probably infected if it contains sequences of commands that are typical of malicious objects (open file, write to file).

Hypervisor

An application supporting the parallel operation of several operating systems on one computer.

iChecker Technology

A technology that allows increasing the speed of anti-virus scanning by excluding objects that have remained unchanged since their last scan, provided that the scan parameters (the databases and the settings) have not been altered. The information for each file is stored in a special database. This technology is used in both real-time protection and on-demand scan modes.

For example, you have an archive file that was scanned by a Kaspersky application and assigned not infected status. Next time, the application will skip this archive unless the archive has been altered or the scan settings have been changed. If you have changed the archive content by adding a new object to it, modified the scan settings, or updated the application databases, the archive will be re-scanned.

Limitations of iChecker technology:

• This technology does not work with large files, since it is faster to scan a file than to check whether the file has been modified since it was last scanned.
• The technology supports a limited number of formats.

Incompatible application

An anti-virus application from a third-party developer or a Kaspersky application that does not support management through Kaspersky Internet Security.

Infected object

An object a portion of whose code completely matches part of the code of known malware. Kaspersky does not recommend accessing such objects.

Kaspersky Security Network (KSN)

The cloud-based knowledge base of Kaspersky containing information about the reputation of applications and websites. Use of data from Kaspersky Security Network ensures faster responses by Kaspersky applications to threats, improves the performance of some protection components, and reduces the likelihood of false positives.

Kaspersky update servers

Kaspersky HTTP servers from which updates of databases and software modules are downloaded.

Keylogger

A program designed for hidden logging of information about keys pressed by the user. Keyloggers function as keystroke interceptors.

License term

A time period during which you have access to the application features and rights to use additional services.

Phishing

A type of Internet fraud aimed at obtaining unauthorized access to users' confidential data.

Probable spam

A message that cannot be unambiguously considered spam, but has several spam attributes (for example, certain types of mailings and advertising messages).

Probably infected object

An object whose code contains portions of modified code from a known threat, or an object whose behavior is similar to that of a threat.

Protected Browser

A dedicated operation mode of a standard browser designed for financial activities and online shopping. Using Protected Browser ensures the safety of confidential data that you enter on the websites of banks and payment systems such as bank card numbers or passwords used for online banking, and also prevents theft of payment assets when making online payments.

Protection components

Integral parts of Kaspersky Internet Security intended for protection against specific types of threats (for example, Anti-Spam and Anti-Phishing). Each of the components is relatively independent of the other ones and can be disabled or configured individually.

Protocol

A clearly defined and standardized set of rules governing the interaction between a client and a server. Well-known protocols and the services associated with them include HTTP, FTP, and NNTP.

Quarantine

A dedicated storage in which the application places backup copies of files that have been modified or deleted during disinfection. Copies of files are stored in a special format that is not dangerous for the computer.

Rootkit

A program or a set of programs for hiding traces of an intruder or malware in the operating system.

On Windows-based operating systems, a rootkit usually refers to a program that penetrates the operating system and intercepts system functions (Windows APIs). Interception and modification of low-level API functions are the main methods that allow these programs to make their presence in the operating system quite stealthy. A rootkit can usually also mask the presence of any processes, folders, and files that are stored on a disk drive, in addition to registry keys, if they are described in the configuration of the rootkit. Many rootkits install their own drivers and services on the operating system (these also are "invisible").

Script

A small computer program or an independent part of a program (function) which, as a rule, has been developed to execute a specific task. It is most often used with programs that are embedded in hypertext. Scripts are run, for example, when you open some websites.

If real-time protection is enabled, the application tracks the execution of scripts, intercepts them, and scans them for viruses. Depending on the results of scanning, you may block or allow the execution of a script.

Security level

The security level is defined as a predefined collection of settings for an application component.

Spam

Unsolicited mass email mailings, most often including advertisements.

Startup objects

The set of programs needed to start and correctly operate the operating system and software installed on your computer. These objects are executed every time the operating system is started. There are viruses capable of infecting autorun objects specifically, which may lead, for example, to blocking of operating system startup.

Task

The functions of the Kaspersky application are implemented in the form of tasks, such as: Full Scan task or Update task.

Task settings

Application settings that are specific for each task type.

Threat level

An index showing the probability that an application poses a threat to the operating system. The threat level is calculated using heuristic analysis based on two types of criteria:

• Static (such as information about the executable file of an application: size, creation date, etc.)
• Dynamic, which are used while simulating the application's operation in a virtual environment (analysis of the application's system calls)

Threat level allows detecting behavior typical of malware. The lower the threat level is, the more actions the application is allowed to perform in the operating system.

Traces

Running the application in debugging mode; after each command is executed, the application is stopped, and the result of this step is displayed.

Traffic scanning

Real-time scanning that uses information from the current (latest) version of the databases for objects transferred over all protocols (for example, HTTP, FTP, and other protocols).

Trust group

A group to which Kaspersky Internet Security assigns an application or a process depending on the following criteria: presence of a digital signature, reputation on Kaspersky Security Network, trust level of the application source, and the potential danger of actions performed by the application or process. Based on the trust group to which an application belongs, Kaspersky Internet Security can restrict the actions that the application may perform in the operating system.

In Kaspersky Internet Security, applications belong to one of the following trust groups: Trusted, Low Restricted, High Restricted, or Untrusted.

Trusted process

A software process whose file operations are not restricted by the Kaspersky application in real-time protection mode. When suspicious activity is detected in a trusted process, Kaspersky Internet Security removes the process from the list of trusted processes and blocks its actions.

Unknown virus

A new virus about which there is no information in the databases. Generally, unknown viruses are detected by the application in objects by using the heuristic analyzer. These objects are classified as probably infected.

Update

The procedure of replacing / adding new files (databases or application modules) retrieved from the Kaspersky update servers.

Update package

A file package designed for updating databases and application modules. The Kaspersky application copies update packages from Kaspersky update servers and automatically installs and applies them.

Virus

A program that infects other programs, by adding its code to them in order to gain control when infected files are run. This simple definition allows identifying the main action performed by any virus: infection.

Vulnerability

A flaw in an operating system or an application that may be exploited by malware makers to penetrate the operating system or application and corrupt its integrity. Presence of a large number of vulnerabilities in an operating system makes it unreliable, because viruses that penetrate the operating system may cause disruptions in the operating system itself and in installed applications.

How to configure DNS over HTTPS protection

Expand all | Collapse all

When you type a website name in the address bar, the browser sends your request to a DNS server. The DNS server determines the IP address of the website requested. Data is transferred from your computer to the DNS server using an ordinary unencrypted text protocol. Intruders can intercept information about the websites you visit and abuse it. To prevent this from happening, this information should be transferred over the secure HTTPS protocol. The server that receives and analyzes such requests is called a DNS over HTTPS (or DoH) server.

Kaspersky Internet Security automatically receives data about which DoH server is used in the Mozilla Firefox browser. If you have added a DoH server manually in the Kaspersky Internet Security application and you want DNS data to be transferred through this DoH server, you need to add this server to your Mozilla Firefox browser settings. For information on configuring the DoH server, see Mozilla Firefox Help.

Special considerations when adding a rule for a network adapter

When you create an allow rule for a network adapter and/or a rule with a specified TTL, this rule may conflict with a deny rule for applications. For example, if an application is in the High Restricted group, it will be denied network access even if you created an allow packet rule for the network adapter (and for TTL).

To configure an allow rule to work for all applications that attempt to connect to the network via this network adapter, you must create the following rules in order of priority from the highest priority to the lowest priority (in the general list of packet rules, the priority is determined from top to bottom, going from the highest priority to the lowest priority).

1. Allow rule for the selected network adapter.
2. Deny rules for all other network adapters.
3. Allow rule without specifying a network adapter.

To configure an allow rule to work for a network adapter using TTL, you must create the following rules in order of priority from the highest priority to the lowest priority:

1. Allow rule for a specific TTL value.
2. Deny rule for a TTL value equal to 255.
3. Allow rule without specifying a TTL value.

Network connections termination

If the computer is shut down or protection is paused when the application is monitoring active network connections, notification about termination of those connections is displayed. This is necessary for properly quitting the application. Termination occurs automatically after 10 seconds or after you click the Yes button. Most terminated connections are recovered after a short time.

If the connection is terminated when you are downloading a file without a download manager, data transmission is interrupted. To download the file, you must start the download process again.

You can cancel termination of connections. To do this, in the notification dialog box, click the No button. The application continues to run.
