After my daugter updated windows 7 to windows 8.1 her AVG 2014 has stopped functioning properly

I had sameproblem. I just went to AVG.com and download A new version. If you have legal license ,it would be free for you. Reistal your AVG with your license key and enjoy. YOu can get AVG 2015 for free.
