Updates

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 The application considers the Anti-Virus databases as outdated after 24 hours, and the Anti-Spam databases after 5 hours from the last update.

For the program to work, it is recommended to update the Anti-Virus and Anti-Spam databases immediately after installing the program. 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.

Kaspersky Security can retrieve database updates from the following update sources:

Updates functionality (including providing anti-virus signature updates and codebase updates), as well as KSN functionality will not be available in the software in the U.S. territory from 12:00 AM Eastern Daylight Time (EDT) on September 10, 2024 in accordance with the restrictive measures.

Database updates can be performed manually or according to schedule.

HTTPS port 443 is used for application database updates.
