About Kaspersky Security Cloud

Kaspersky Security Cloud provides flexible protection against various types of information security threats, network and phishing attacks, and spam. Various features and protection components are available as part of Kaspersky Security Cloud.

Some protection components are not included in the application installation package and must be downloaded from the Internet. Such components include the password protection application Kaspersky Password Manager and the child protection application Kaspersky Safe Kids.

Computer Protection

Each type of threat is handled by a dedicated protection component. You can enable and disable protection components, and configure their settings.

In addition to the real-time protection provided by the security components, we recommend that you regularly scan your computer for viruses and other malware. This is necessary in order to prevent any possible spreading of malicious programs that have not been discovered by protection components, for example, because a low security level was set or for other reasons.

To keep Kaspersky Security Cloud up to date, you need to update the databases and application modules used by the application.

Some specific tasks that should be run occasionally (such as removal of traces of a user's activities in the operating system) are performed by using advanced tools and wizards.

What follows is a description of the logic of how the protection components interact when Kaspersky Security Cloud has been set to the mode that is recommended by Kaspersky Lab specialists (in other words, with the default application settings).

File Anti-Virus

File Anti-Virus prevents infection of the computer's file system. The component starts upon startup of the operating system, continuously remains in the computer's RAM, and scans all files that are opened, saved, or launched on your computer and all connected drives. Kaspersky Security Cloud intercepts each attempt to access a file and scans the file for known viruses and other malware. Further access to the file is allowed only if the file is not infected or is successfully disinfected by the application. If a file cannot be disinfected for any reason, it is deleted. A copy of the file is moved to Quarantine when that happens. If an infected file is placed in the same location where the deleted file with the same name used to be, Quarantine saves only a copy of the last file. A copy of the previous file with the same name is not saved.

Mail Anti-Virus

Mail Anti-Virus scans incoming and outgoing email messages on your computer. An email message is available to the recipient only if it does not contain dangerous objects.

Web Anti-Virus

Web Anti-Virus intercepts and blocks the execution of scripts on websites if they pose a threat. Web Anti-Virus also monitors all web traffic and blocks access to dangerous websites.

IM Anti-Virus

IM Anti-Virus ensures the safe use of IM clients. The component protects information that comes to your computer via IM protocols. IM Anti-Virus ensures safe operation of various applications for instant messaging.

Application Control

Application Control logs actions performed by applications in the operating system, and manages applications' activities based on the group to which the component has assigned an application. A set of rules is specified for each group of applications. These rules manage the applications' access to various operating system resources.

Application Manager

Application Manager lets you manage applications installed on the computer.

Webcam Protection

Webcam Protection blocks unauthorized access to the webcam and notifies you that access has been blocked.


Firewall ensures your security when you use local networks and the Internet. The component filters all network activities by using rules of two types: rules for applications and packet rules.

Network Monitor

Network Monitor is designed for monitoring network activity in real time.

System Watcher

The System Watcher component rolls back the changes made to the operating system by malicious or other activity of applications.

The component protects against malware, including:

Disabling this component is not recommended.

Network Attack Blocker

Network Attack Blocker loads at operating system startup and tracks incoming network traffic for activities characteristic of network attacks. When an attempt to attack your computer is detected, Kaspersky Security Cloud blocks all network activity from the attacking computer that is aimed at your computer.


Anti-Spam scans incoming email messages for spam. All messages containing spam are marked with a special header.


Anti-Phishing allows checking URLs to find out if they are included in the list of phishing URLs. This component is built into Web Anti-Virus, Anti-Spam, and IM Anti-Virus.


Anti-Banner blocks ad banners on websites and in application interfaces.

Private Browsing

Private Browsing detects requests sent by the browser to tracking services and can modify requests to and responses from tracking services in a way that protects you from tracking of your online activity.

Safe Money

Safe Money provides protection of confidential data when using online banking services and payment systems, and prevents theft of funds when making online payments.

On-Screen Keyboard

On-Screen Keyboard prevents interception of data entered on the hardware keyboard and protects personal data against interception attempts that use screen shots.

Trusted Applications mode

Trusted Applications mode protects the computer from applications that may be unsafe. When Trusted Applications mode is enabled, Kaspersky Security Cloud allows running only applications that are identified as trusted (for example, based on information about an application from Kaspersky Security Network, or a trusted digital signature).

My Kaspersky

If a computer has Kaspersky Security Cloud installed, you can manage protection of this computer remotely from My Kaspersky portal.

Backup and Restore

Backup and Restore functionality is designed to protect your data against loss as a result of hardware failures. Kaspersky Security Cloud can perform scheduled data backups to removable drives, network and online storages. You can copy files by category and specify the number of versions of the same file to store.

Data Encryption

Data Encryption is designed to protect your confidential data against unauthorized access. You can unlock a data vault and view its contents only after entering a password.

Weak settings control

Operating system settings can directly affect the security of your device. Kaspersky Security Cloud detects weak settings of the operating system and prompts you to fix them.

Devices in my network

Kaspersky Security Cloud shows which devices are connected to your Wi-Fi network. This lets you prevent unauthorized devices from connecting to your network.

Hard Drive Health Monitor

Kaspersky Security Cloud constantly monitors the health of your hard drives using S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology). If the health of one or more hard drives gets worse, the application notifies you and offers you to copy your data from the damaged drives to other media to avoid data loss.

Account Check

The Account Check component allows to check your accounts being used to sign in to various websites to determine possible leaks of your data to the public domain.

Secure Connection

Kaspersky Security Cloud protects your data on connection to unsecured Wi-Fi networks.
