Databases of the Anti-Virus, Anti-Spam, and Anti-Phishing modules (hereafter also referred to as 'databases') are files containing records that can be used to detect malicious code in scanned objects. These records contain information about the control sections of malicious code and algorithms used for disinfecting objects that contain such threats.
Virus analysts at Kaspersky Lab detect hundreds of new threats daily, create records to identify them, and include them in database updates packages (or update packages). Update packages consist of one or several files containing records to identify threats that were detected since the previous update package was released. In order to minimize the risk of infecting the protected mail server, we recommend that you receive database update packages regularly.

This task is started each time an update package is downloaded to the storage of Kaspersky Security Center Administration Server, and it lets you update the anti-virus databases on all SVMs. You can use the automatically created anti-virus database update task. If necessary, you can change the settings of this task or delete it, and configure the anti-virus database update task for SVMs of one or several KSC clusters belonging to one administration group.
