Program databases ("databases") are files with records used by the program components and modules to detect events occurring in your organization's IT infrastructure.
Virus analysts at Kaspersky detect hundreds of new threats daily (including "zero-day" exploits), create records to identify them, and include them in database updates packages ("update packages"). Update packages consist of one or more files containing records to identify threats that were detected since the previous update package was released. We recommend that you regularly receive update packages. When the program is installed, the database release date is the same as the program release date, and therefore you must update the databases immediately after installing the program.
The program periodically automatically checks for new update packages on the Kaspersky update servers (once every 30 minutes). By default, if for some reason program databases are not updated for 24 hours, Kaspersky Anti Targeted Attack Platform displays this information in the Dashboard section of the window of the program web interface.
