Update

During the license period you can download updates for the databases of Kaspersky Anti-Virus.

Databases are files containing records that are used to detect the malicious code of known threats in scanned objects. These records contain information about the control sections of the threats' code and algorithms used for disinfecting objects in which these threats are contained.

Virus analysts at Kaspersky Lab detect hundreds of new threats daily, create records to identify them, and include them in database updates. Database updates are one or several files containing records identifying threats that were detected during the time since the previous update was released. In order to minimize the risk of infecting the server, we recommend that you receive database updates regularly.

Kaspersky Lab can release Anti-Virus module update packages. Update packages are classified as urgent (or critical) or routine. Urgent update packages remove vulnerabilities and fix errors; routine updates add new functions or improve existing ones.

During license validity period you can download updates from the web site of Kaspersky Lab and install them manually.

You can also automatically set module updates for other Kaspersky Lab applications using a secure server as a medium to distribute the updates.

Database updates

During installation the Anti-Virus has retrieved the current databases from an Kaspersky Lab's HTTP server; if you have configured automatic database update, Kaspersky Anti-Virus starts the update according to the schedule (once every 30 minutes) using the predefined update task (ID=6).

You can configure the preinstalled update task and create user-defined update tasks.

If update downloading is interrupted or terminates with an error, Kaspersky Anti-Virus automatically switches to using databases with previously installed update. If Kaspersky Anti-Virus databases get corrupted, you can roll them back to the previously installed updates.

By default, if Kaspersky Anti-Virus databases have not been updated for a week since the moment when Kaspersky Lab had released the last installed updates, the Anti-Virus logs the event Databases are outdated (AVBasesAreOutOfDate). If the databases have not been updated within two weeks, it registers the event Databases are obsolete (AVBasesAreTotallyOutOfDate). You can configure administrator notification about these events.

Copying database and module updates. Distributing updates

You can download updates to each protected server or use one computer as an intermediary by copying all updates onto it and then distributing them to the servers. And if you use Kaspersky Security Center for the centralized administration of computer protection in an enterprise, you can use the Kaspersky Security Center Appendix as an intermediary for distributing updates.

To save database updates on an intermediary computer without applying them, configure updates distribution in the update task.
