File Anti-Virus
File Anti-Virus prevents infection of the computer's file system.

When you or an application attempt to access a file included in the protection scope, File Anti-Virus checks iSwift databases for information about the file, and uses this information to decide whether to scan the file.
Recognizing malicious objects is possible thanks to signature analysis, a way of searching for threats based on threat descriptions included in the anti-virus databases. In addition to signature analysis, File Anti-Virus uses heuristic analysis and other scanning technologies.
After detecting an object, the application displays a notification about it and performs an action on the object based on your File Anti-Virus settings.

Before attempting to disinfect or delete an infected file, the Kaspersky application saves a backup copy for subsequent restoration or disinfection. A file copy appears in Quarantine. You can try to disinfect this file later by using updated anti-virus databases.
Information about File Anti-Virus operation and all detected objects is logged in a report.
Note: If File Anti-Virus stops running with an error, you can view the report and try to start the component again. If the problem is not solved, you can contact Kaspersky Customer Service.
