How can I upgrade my product to Panda 2013?

[TaTienDo]

I have a Panda 2012, 2011, 2010 or 2009* product installed and with active services and I would like to switch to the new Panda 2013 product.

*NOTE: This information applies only to commercial versions of Panda's products (boxed or online version).

To upgrade your Panda antivirus to Panda 2013 completely free, simply install the latest Panda 2013 version without uninstalling your current product. The remaining time on your license period will be carried over and what's more, you will enjoy the benefits of a higher-end product.
