Data is protected using the following algorithm:
1. Each web page or file that is accessed by the user or an application via the HTTP, HTTPS or FTP protocols, is
intercepted and analyzed for malicious code by Web Anti-Virus. Malicious objects are detected using both
Kaspersky Anti-Virus databases and the heuristic algorithm. The database contains descriptions of all the
malicious programs known to date and methods for neutralizing them. The heuristic algorithm can detect new
viruses that have not yet been entered in the database.

it.
Scripts are scanned according to the following algorithm:
1. Each script run is intercepted by Web Anti-Virus and is analyzed for malicious code.
2. If the script contains malicious code, Web Anti-Virus blocks this script and informs the user of it with a special
pop-up message.
3. If no malicious code is discovered in the script, it is run.
Web Anti-Virus intercepts only scripts using the Microsoft Windows Script Host functionality.
