Step 1. Create a restore point

Step 2. Make sure you have an activation code for your Kaspersky product
After you create a restore point, make sure you have a 20-digit activation code for your Kaspersky Lab product. 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 in a box, you will see the activation code on the Quick Start Quide you find in the box.
If you bought the product online, the activation code will be in the e-mail from the online store.
If you lost the activation code, please contact Technical Support via My Kaspersky (requires registration).
Step 3. Delete the files of the earlier installed product versions
- Download the removal tool for Kaspersky Lab products.
- The downloaded file will apper in the lower part of the browser window. Run the file.
- The tool window opens. To continue, click I agree.
- The removal tool will search for remaining files of previously installed Kaspersky Lab products. For successful installation, please remove all detected files. Select the file from the list, type the code from the image and click Remove.
If you installed the 2015 version earlier, manually select Kaspersky Anti-Virus \ Internet Security \ Kaspersky Total Security 126.96.36.1991 in the drop-down list. Other product versions are detected automatically.
- Confirm the removal.
- Click OK to restart your computer.
