How to update the application

The application is updated automatically if you select run mode Automatically in the update settings window (Database Update → Databases update schedule).

The application is automatically updated if you install a new version of the application over the previous one.

If you have a current license for an earlier version of Kaspersky Anti-Virus, you do not need to activate the application. The Setup and Removal Wizard will automatically retrieve information about the license for the previous version of Kaspersky Anti-Virus and apply it during installation of the new version of Kaspersky Anti-Virus.

While downloading the update, the application compares the previous and new versions of the End User License Agreement, Kaspersky Security Network Statement, and Statement regarding data processing for marketing purposes. If the agreements and/or statements differ, the application offers you to read and accept them again.

The application can be upgraded if the following versions of Kaspersky Anti-Virus are installed on your computer:

• Kaspersky Anti-Virus 2015
• Kaspersky Anti-Virus 2016
• Kaspersky Anti-Virus 2017
• Kaspersky Anti-Virus 2018
• Kaspersky Anti-Virus 2019
• Kaspersky Anti-Virus 2020

When upgrading, the license that was used in the previous version of the application from this list will be automatically applied in the new version of the application. Upgrades from earlier versions of the application are not supported.

Limitations on upgrades from a previous version of the application

After an upgrade from a previous version, Kaspersky Anti-Virus starts automatically even if automatic startup of the application is disabled in the settings that have been saved. When the operating system restarts afterwards, Kaspersky Anti-Virus does not start automatically if automatic startup of the application is disabled in the settings that have been saved.

When a previous version of Kaspersky Anti-Virus is upgraded, the following application settings are replaced with default settings:

• Kaspersky Anti-Virus display settings
• Scan schedule
• Participation in Kaspersky Security Network
• File Anti-Virus protection level
• Mail Anti-Virus protection level
