Hi David,
I'm sorry to hear this is happening. I'd recommend restaring your computer into Windows Safe Mode with Networking (http://avgclick.me/rebootintosafemode) a try uninstalling AVG (http://avgclick.me/UninstallAVGAV)from there.
Let me know how it goes.
Please! I need an answer! Thanks !!!
Hi David,
Did you try AVG Removal Tool? If not, Download it From the link below and run it. It will guide you to uninstallation Procedure
Install AVG on your PC, Mac | AVG installation files
Thanks.

I still can´t uninstall AVG and noone here answers me. I need to uninstall so I can install a new antivirus. There should be easy. I never had any problem with AVG until this version. If you don´t want to provide a free service that´s ok but let me uninstall it. Thank you.
