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 even before you open a web address or download a file, as soon as your computer establishes an Internet connection.
The Web Anti-Virus component protects information that your computer sends and receives via the HTTP and HTTPS protocols in Safari, Google Chrome or Firefox browsers.
Note: Web Anti-Virus monitors web traffic on the ports that are most frequently used for HTTP and HTTPS data transfer.
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 Lab. When Web Anti-Virus detects a threat, it performs the action that you specify. Malicious objects are recognized using signature analysis, heuristic analysis, and data from Kaspersky Security Network.
Select the action that Web Anti-Virus performs after detecting dangerous web traffic objects
Checking links on webpages for phishing and for malicious web addresses makes it possible to avoid phishing attacks. Phishing attacks usually happen in 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 and malicious web addresses, Kaspersky Internet Security uses the anti-virus databases of the application, heuristic analysis, and data from Kaspersky Security Network.
