How to upgrade the application

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

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 Internet Security are installed on your computer:

• Kaspersky Internet Security 2013
• Kaspersky Internet Security 2014
• Kaspersky Internet Security 2015
• Kaspersky Internet Security 2016
• Kaspersky Internet Security 2017
• Kaspersky Internet Security 2018
• Kaspersky Internet Security 2019

Limitations on upgrades from a previous version of the application

Upgrading from Kaspersky Internet Security has the following limitations:

• When a previous version of Kaspersky Internet Security is upgraded, the following application settings are replaced with default settings:
  • Kaspersky Internet Security display settings
  • Scan schedule
  • Participation in Kaspersky Security Network
  • File Anti-Virus protection level
  • Mail Anti-Virus protection level
  • Anti-Banner settings
  • Update sources
  • List of trusted web addresses
  • URL Advisor settings
• After an upgrade from a previous version, Kaspersky Internet Security 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 Internet Security does not start automatically if automatic startup of the application is disabled in the settings that have been saved.

When updating Kaspersky Internet Security 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 Internet Security 2013, 2014, 2015 to a new version, the new version of Kaspersky Internet Security will use the default application settings.
