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 Internet Security, 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 Internet Security and apply it during installation of the new version of Kaspersky Internet Security.

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 Internet Security are installed on your computer:

• Kaspersky Internet Security 2015
• Kaspersky Internet Security 2016
• Kaspersky Internet Security 2017
• Kaspersky Internet Security 2018
• Kaspersky Internet Security 2019
• Kaspersky Internet Security 2020
