How to upgrade the application

The application is updated automatically. If you have a current license for an earlier version of Kaspersky Anti-Virus, you do not need to activate the application: the Setup 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.

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

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 2013
• Kaspersky Anti-Virus 2014
• Kaspersky Anti-Virus 2015
• Kaspersky Anti-Virus 2016
• Kaspersky Anti-Virus 2017
• Kaspersky Anti-Virus 2018
• Kaspersky Anti-Virus 2019

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
• Update sources
• List of trusted web addresses
• URL Advisor settings

When updating Kaspersky Anti-Virus 2013, 2014, 2015 to a new version, the old license is not always applicable. This is due to licensing specifics in these application versions. Also, when updating Kaspersky Anti-Virus 2013, 2014, 2015 to a new version, the new version of Kaspersky Anti-Virus will use the default application settings.
