Your PC’s file system may contain viruses and other Malware. Malware may be stored in your file system for years, having intruded your computer from a removable drive or from the Internet and does not show itself. But as soon as you open an infected file or try to copy it on a disk, the virus starts to function.
File Anti-Virus is a component that controls computer file system. It scans OPEN, LAUNCHED AND SAVED files on your computer and on all attached discs. Each file the user deals with is intercepted by a Kaspersky Lab productand scanned for viruses. The user can work with the file if the file is not infected or was successfully disinfected by a Kaspersky Lab product. If the file cannot be disinfected by some reasons, it is either deleted or quarantined.
