Upgrade Your Product

As a Kaspersky Lab customer, you may upgrade to our latest security software version at no cost, as long as you have time remaining on your existing license.

If you have a version of Kaspersky Internet Security, for example, with an active license, you can upgrade to the latest version of Internet Security.
