File Anti-Virus
File Anti-Virus prevents infection of the computer's file system. The component starts during startup of the operating system, remains in the RAM of the computer, and scans all files that are opened, saved, or run on your computer and on all connected drives for viruses and other malware. If you disable File Anti-Virus, it will not start at operating system startup. You will have to re-enable File Anti-Virus manually.

When the user or an application attempts to access a protected file, File Anti-Virus checks the iSwift databases for information about the file, and uses this information for deciding whether to scan the file.
Recognizing malicious objects is possible thanks to the use of signature analysis, a way of searching for threats based on threat descriptions included in the anti-virus databases of the application. In addition to signature analysis, File Anti-Virus uses heuristic analysis and other scanning technologies.
If a threat is detected in a file, Kaspersky Internet Security assigns one of the following status labels to the file:
- A status that indicates the type of the malicious program detected (for example, virus or Trojan).
- Probably infected status, if the scan cannot determine whether or not the file is infected. The file may contain a code sequence that is typical of viruses and other malware, or modified code from a known virus.
After assigning a status the application displays a notification about the detected object and takes the action on the object based on your File Anti-Virus preferences.
Select the action that File Anti-Virus performs after detecting an infected or probably infected file
- In the menu bar, click the application icon.
- In the menu that appears, choose Preferences.
The application preferences window opens.
- On the Protection tab, in the File Anti-Virus section, select the action that File Anti-Virus performs after detecting an infected or probably infected file.
Before attempting to disinfect or delete an infected file, Kaspersky Internet Security saves a backup copy for subsequent restoration or disinfection. A file copy is moved to Quarantine. Probably infected files are also placed in Quarantine. You can try to disinfect those files later by using updated anti-virus databases.
Information about File Anti-Virus operation and all detected objects is logged in a report.
