Updates of Kaspersky Security application databases keeps Microsoft Exchange server protection up to date.
New viruses and other threats as well as new kinds of spam appear on a daily basis worldwide. Information about threats and spam and ways to neutralize them is contained in the application databases, namely the Anti-Virus and Anti-Spam databases. Application databases have to be updated regularly to enable timely detection of threats and spam messages. The application considers the Anti-Virus databases as outdated after 24 hours, and the Anti-Spam databases after 5 hours from the last update.
You are advised to update the application databases immediately after installation, as the databases included in the distribution kit may be out of date by the time you install your application. The anti-virus databases on Kaspersky update servers are updated every hour. The Anti-Spam database is updated every five minutes. You are advised to set up automatic database updates to run with the same frequency.

Database updates can be performed manually or according to schedule.
