Switching to permanent use of Kaspersky Internet Security

If you want to switch to permanent use of Kaspersky Internet Security, you must purchase a license for Kaspersky Internet Security and then activate the application.

To purchase a license for Kaspersky Internet Security:

1. Open the main application window.
2. In the More Tools drop-down list, select Upgrade.
3. Click the Purchase license link to go to the website of the Kaspersky eStore or a partner company on which you can purchase a license for Kaspersky Internet Security.

When used in certain regions or by subscription, Kaspersky Anti-Virus does not allow switching to the trial version of Kaspersky Internet Security. In these cases, the Upgrade item is not available.
