Kaspersky Internet Security provides comprehensive protection against various types of information security threats, network and phishing attacks, and spam. Various functions and protection components are available as part of Kaspersky Internet Security to deliver comprehensive 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 Internet Security 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 Internet Security has been set to the mode that is recommended by Kaspersky Lab specialists (in other words, with the default application settings).
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 Internet Security 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 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 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 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 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 lets you manage applications installed on the computer.
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 is designed for monitoring network activity in real time.
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 Internet Security 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 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 provides protection of confidential data when using online banking services and payment systems, and prevents theft of funds when making online payments.
Secure Data Input
Secure Keyboard Input provides protection from keyloggers for personal data entered on websites. 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 Internet Security 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).
Parental Control is designed to protect children and teenagers from threats related to computer and Internet use.
Parental Control allows you to set flexible restrictions on access to web resources and applications for different users depending on their age. In addition, Parental Control allows viewing statistical reports on the activities of controlled users.
