You can try to restore
your computer, and seriously consider removing AVG and using something better, such as MSE
The choice is yours, please don't feel like I am pressuring you, just a recommendation. To remove AVG, use the correct uninstaller from AVG: AVG | Download tools and utilities
If you do not want to remove AVG, I would recommend bugging them until someone gives you the help you need, or waiting here for some other help from another member.
Do make sure windows is completely updated for compatability and stability reasons.
