Changing OS on one of my computers

Hello Alena.
Thanks for being so specific about your post. I request you to proceed with the fresh installation of AVG after the new operating system is installed.
Thank you.

Hello. I need to "refresh" my old operating system (WINDOWS XP) on one of my computers, switching it to Windows 8.1. I purchased a 2-year-AVG license for 1 desktop PC and 2 netbooks. Should I disactivate my current license and then download AVG again once I have the new OS on my desktop? Thank you for your help!
