About Kaspersky Anti-Virus
Aug 29, 2019
Kaspersky Anti-Virus provides comprehensive protection against various types of information security threats. Various functions and protection components are available as part of Kaspersky Anti-Virus 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 Anti-Virus 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 Anti-Virus has been set to the mode that is recommended by Kaspersky 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 Anti-Virus 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.
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:
- Screen lockers
- Ransomware that encrypts data or blocks access to files or the system and extorts ransom for restoring the files or access to them
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 Anti-Virus blocks all network activity from the attacking computer that is aimed at your computer.
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 and IM Anti-Virus.
On-Screen Keyboard prevents interception of data entered on the hardware keyboard and protects personal data against interception attempts that use screen shots.
If a computer has Kaspersky Anti-Virus installed, you can manage protection of this computer remotely from the My Kaspersky website.
Kaspersky Anti-Virus protects your data on connection to unsecured Wi-Fi networks.
