The Actual Upgrade Method
The upgrade method for the 2010 version is extremely simple! First, keep in mind that to upgrade it to the new version for free, you
need the valid license key that had arrived with your previous version of Kaspersky Internet. As long as your previous version’s license is active, you are entitled to all the version upgrades and signatures. This is the reason it is imperative for you to have the license key saved somewhere on your computer, a CD or a USB stick. If you have lost the key, you will have to get a replacement code by contacting the Kaspersky Helpdesk.
If you have found the license key, download the correct upgrade version from Kaspersky Lab. When you go to this website, select “Kaspersky Internet Security" from the list and download the file.
When the file finishes downloading, double-click it to run.
Now a “Setup Wizard" will appear, which will walk you through the entire upgrading procedure. During the upgrading, you will be required to enter the license key from the previous version.
Once installed, reboot your computer. Since the 2010 version will replace the previous version, your activation information and the anti-spam database will automatically be relocated in the respective folder.
