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.

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 are using a proxy server, you need to configure the proxy server settings.

Updates are downloaded over the HTTPS protocol. They may also be downloaded over the HTTP protocol when it is impossible to download updates over the HTTPS protocol.

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

  • Kaspersky Endpoint Security databases. Computer protection is provided using databases that contain signatures of viruses and other threats and information on ways to neutralize them. Protection components use this information when searching for and neutralizing infected files on your computer. The databases are constantly updated with records of new threats and methods for counteracting them. Therefore, we recommend that you update the databases regularly.

    In addition to the Kaspersky Endpoint Security databases, the network drivers that enable the application's components to intercept network traffic are updated.

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

While updating, the application modules 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).

Information about the current state of the Kaspersky Endpoint Security databases is displayed in the main application window or the tooltip that you see when you hover the cursor over the icon of the application in the notification area.

Information on update results and on all events that occur during the performance of the update task is logged in the Kaspersky Endpoint Security report.
