Anti-virus database update sources

An update source is a resource containing updates for Kaspersky Anti-Virus databases. Update sources can be HTTP or FTP servers, and local or network folders.
Kaspersky Anti-Virus copies anti-virus database updates over the Internet from Kaspersky Lab update servers or from an FTP / HTTP server or from a network resource specified by the administrator. The updates that are received are stored on the server in the kavcommon\updater service folder (under Linux operating systems – in kavcommon/updater). This directory is created when the application is installed and stored at the following address:
- under Microsoft Windows operating systems – in the Lotus Domino server's directory of binary files (default path: C:\Program Files\IBM\Lotus\Domino);
- under Linux operating systems – in the Lotus Domino server's data directory (default path: /local/notesdata).
Updates received from one of the servers can be used to update Kaspersky Anti-Virus installed on other Domino servers. To this end, the kavcommon\updater\retranslation service folder must be specified as the update source (under Linux operating systems – kavcommon/updater/retranslation), which is located on the update source server at the following address:
- under Microsoft Windows operating systems – in the Lotus Domino server's directory of binary files (default path: C:\Program Files\IBM\Lotus\Domino);
- under Linux operating systems – in the Lotus Domino server's data directory (default path: /local/notesdata).
If Kaspersky Anti-Virus is installed on several servers, one of them can copy updates over the Internet and the others can access the network resource on which this server placed the newly-received updates.
During the update process Kaspersky Anti-Virus compares the anti-virus databases located on the server and in the update source. If the anti-virus databases differ in content, the missing section is copied from the update source. The fact that not all the databases are downloaded significantly increases the speed of copying files and considerably reduces Internet traffic.
Loading of updates can be scheduled or manual. Information about events registered by Kaspersky Anti-Virus during the update process is recorded in the Event log and statistics database.
You can configure the update settings for several servers by using a profile, or set values for each server individually.
If Kaspersky Lab update servers are unavailable (for example, your Internet connection is down), contact Kaspersky Lab Technical Support Service to receive the updates in ZIP format. You can copy the updates to an FTP or HTTP site, or save them in a local or network folder.
