The set of available protection features may vary depending on the application tier.
Kaspersky application provides comprehensive protection against viruses, network attacks, phishing, personal data breaches, and other kinds of cybersecurity threats. Various functions and protection components are available as part of Kaspersky application 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 application up to date, databases and application modules must be regularly updated.
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 application 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.
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 application blocks all network activity from the attacking computer that is aimed at your computer.
Safe Browsing
Safe Browsing intercepts and blocks the execution of scripts on websites if they pose a threat. Safe Browsing also monitors all web traffic and blocks access to dangerous websites.
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.
Firewall
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.
Firewall is only available on Kaspersky Standard, Kaspersky Plus, and Kaspersky Premium plans.
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.
Anti-Phishing
Kaspersky application protects your from visiting phishing websites. A phishing website is a fraudulent website that looks like the website of a bank, payment system, cryptocurrency trading platform, or another legitimate website. It can be fairly hard to tell a phishing website from a legitimate one based on its look. Visiting a phishing website can result in theft of passwords, bank card information, and other sensitive personal data.
