How to update application databases and modules

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

Current application license is required for regular database updates. If there is no current license, you will only be able to perform one update.

During the update process, the databases and application modules are downloaded and installed on your device.

You can get updates for databases and application modules from Kaspersky update servers, from local or network directories, and from other update sources.

During an update, the application modules and databases on your device are compared with 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 portions of the updates will be installed on your device.

If the databases are obsolete, the update package may be large, which may cause additional Internet traffic (up to several dozen MB). Up to 3 GB of disk space may be used.

Updates are downloaded from Kaspersky update servers or from other FTP, HTTP, or HTTPS servers over standard network protocols. By default, Internet connection settings are determined automatically. If you use a proxy server, you need to specify the proxy settings in the general application settings.

Regardless of the update source, the update package is downloaded and the database and application module updates are installed on the device using the Update task.

An Update predefined task is created in the application. Using this task, you can perform scheduled and on-demand updates of databases and application modules and configure update settings.

You can also create update user tasks on the command line.

You can configure the following settings for updating databases and application modules:

• Select the source from which the application will receive updates, depending on the update scenario used.
• Configure the response timeout of a selected update source when attempting to connect to it. If an update source does not respond within the specified time, the application contacts the next update source in the list.
• Select the mode of downloading and installing application modules and application version updates: download and install, download only, or do not download.
• Configure the task run schedule for updates. By default, the application updates the databases once every 60 minutes.

In the application interface, you can update databases and application modules using the Update task. You can start and stop the task.

The application interface also lets you:

• Monitor the progress of the Update task.
• View pop-up notifications about the status of the Update task; in these notifications, you can click the Open Reports link to navigate to application component reports and scan task results.
• View a report with the result of the Update task.

  The result of the Update task is displayed in the report in the Update section.
