From Kaspersky Labs
Note: From August 1, 2012 Kaspersky Lab stops releasing anti-virus databases in zip-archives. You can now use the update utility available from our download page for Kaspersky Antivirus.
It is essential to update your antivirus databases on a regular basis. If you do not, your antivirus program will not detect the latest malicious programs. Therefore, we release updates every hour to ensure that users are protected against the latest malware.
In February 2005, we stopped issuing large cumulative updates. All antivirus database files can now be updated hourly; this means that we are able to rapidly update the files and users of our products can access these new files.
All users are strongly encouraged to use the integrated automatic download function.
This update module determines exactly which update files your solution needs. This reduces the amount of information you will need to download from our servers.
