Kaspersky Anti-Virus 8.0.0.454 - User Guide and FAQ

Frequently Asked Questions - Kaspersky Anti-Virus

1. Kaspersky Anti-Virus does not rescan files that have been scanned earlier. Why?
   This is true. Kaspersky Anti-Virus does not rescan files that have not changed since the last scan.
   
   That has become possible due to new iChecker and iStreams technologies. The technology is implemented in the program using a database of file checksums and file checksum storage in alternate NTFS streams.
   
   
2. Why do I need the key file? Will my copy of the anti-virus application work without it?
   No, Kaspersky Anti-Virus does not work without a license key.
   
   If you are still deciding whether or not to purchase Kaspersky Anti-Virus, we can provide you with a temporary key file (trial key), which will only work either for two weeks or for a month. When this period expires, the key will be blocked.
   
   
3. What are the daily updates for?
   A few years ago viruses were transmitted on floppy disks, and adequate computer protection could be achieved by installation of an anti-virus program followed by rare updates to its anti-virus database. However, recent virus epidemics spread around the world in several hours, and anti-virus protection with old database may be helpless against a new threat. In order to resist new viruses, you should update the anti-virus database on a daily basis.
