About database and application module updates

Updating the databases and application modules of Kaspersky Endpoint Security ensures up-to-date protection on your computer. New viruses and other types of malware appear worldwide on a daily basis. Kaspersky Endpoint Security databases contain information about threats and ways of neutralizing them. To detect threats quickly, you are urged to regularly update the databases and application modules.

Regular updates require a license in effect. If there is no current license, you will be able to perform an update only once.

The main update source for Kaspersky Endpoint Security is Kaspersky update servers.

Your computer must be connected to the Internet to successfully download the update package from Kaspersky update servers. By default, the Internet connection settings are determined automatically. If you use a proxy server, you need to adjust the connection settings.

While performing an update, the following objects are downloaded and installed on your computer:

• Kaspersky Endpoint Security databases. During installation, Kaspersky Endpoint Security downloads the latest databases from one of the Kaspersky HTTP update servers. If the predefined task with default settings (ID=6) is used for updating, Kaspersky Endpoint Security updates the databases once every 60 minutes. You can edit the settings of the predefined task for database and application module updates and create custom update tasks.

  Kaspersky Endpoint Security continues to use the previously installed database version if the database update download is interrupted or ends with an error. If no previously installed databases are available, then the application continue functioning in the without databases mode. Updating the databases and application modules is still available.

  By default, the application logs the Databases are out of date event (AVBasesAreOutOfDate) if the last installed database updates were published on the Kaspersky server more than three days, but less than seven days ago. If the databases have not been updated for seven days, Kaspersky Endpoint Security logs the event Databases are obsolete (AVBasesAreTotallyOutOfDate). The database is up-to-date if it was downloaded less than three days ago.

• Application updates. In addition to the databases of Kaspersky Endpoint Security, you can also update the application. Updating the application fixes vulnerabilities in Kaspersky Endpoint Security or enhances existing functions.

  The application update can be installed regardless the state of the application (started or stopped, managed by a Kaspersky Security Center policy) and update scheduling.

  Kaspersky Endpoint Security continues protecting your computer during the application update procedure.

  Kaspersky Endpoint Security migrates the application settings and event log automatically. The settings form the previous application version are exported on the start of the updated version.

  In case Kaspersky Endpoint Security functions incorrectly after the application update installation, the application is automatically rolled back to the previous version. A message about the application update rollback is displayed. We recommend contacting Kaspersky Technical Support.

While updating, the application and databases on your computer are compared against the up-to-date version at the update source. If your current databases and application modules differ from their respective up-to-date versions, the missing portion of the updates is installed on your computer.

If the databases are obsolete, the update package may be large, which may cause additional Internet traffic (up to several dozen MB).
