Step 2. Make sure you have an activation code for your Kaspersky application

After you create a restore point, make sure you have a 20-digit activation code for your Kaspersky application. You will need to enter it after you reinstall the application.

The code contains Latin letters and numerals divided into four groups of 5 characters.

If you bought the product offline on a CD, you will see the activation code on the Quick Start Guide you find in the box.
