Poor performance

Hello Vic. Sorry to hear about the inconvenience caused. Please have a look at this article: http://avgclick.me/restorechangesbyAVGPCTuneup

This morning AVG Tune up asked to correct over 1000 errors in my browser (Firfefox).  I clicked OK, now the browers runs slowly, some videos on Facebook actually stop running.  I just switched over to Firefox 2 days ago and I find it hard to believe it has over 1000 errors already.  How can I fix this?
