Web Anti-Virus

When you use the Internet, the information on your computer is at risk of infection by viruses and other computer security threats. Computer security threats may penetrate your computer when you download free programs or visit websites that have been attacked by hackers. In addition, network worms may attack your computer as soon as your computer establishes an Internet connection, even before you open a web address or download a file.

The Web Anti-Virus component protects information that your computer sends and receives via the HTTP and HTTPS protocols in Safari, Chrome, or Firefox.

Note: Web Anti-Virus monitors web traffic on the ports most frequently used for HTTP and HTTPS data transfer.

Enable/disable Web Anti-Virus

Important: If you have disabled Web Anti-Virus, it will not be re-enabled automatically when Kaspersky Internet Security starts again or when the operating system restarts. You have to re-enable Web Anti-Virus manually.

Web Anti-Virus scans web traffic based on the settings recommended by Kaspersky. Malicious objects are recognized using signature analysis, heuristic analysis, and data from Kaspersky Security Network.

Checking links on webpages for phishing threats and malicious web addresses makes it possible to avoid phishing attacks. Phishing attacks usually take the form of email messages from criminals, who pretend to be financial institutions (such as banks) and send links to fraudulent websites. In these emails, the criminals try to trick the user into visiting a phishing website and entering confidential data (such as your bank card number or the name and password for your online bank account). A phishing attack can be disguised, for example, as a message from your bank with a link to its official website, but in reality the link takes you to an exact copy of the bank's official website created by impostors.

Web Anti-Virus monitors your web traffic for attempts to visit a phishing website; it blocks access to such websites. To check links on webpages for phishing threats and malicious web addresses, Kaspersky Internet Security uses the application databases, heuristic analysis, and data from Kaspersky Security Network.

Web traffic scan algorithm

Each website or file that you or an application accesses via the HTTP and HTTPS protocols is intercepted and scanned for malicious code by Web Anti-Virus:

Information about Web Anti-Virus operation and all detected dangerous web traffic objects is logged in a report.

Note: If Web Anti-Virus stops running with an error, you can view the Web Anti-Virus report and try to restart the component. If the problem is not solved, you can contact Kaspersky Technical Support.
