The reason I'm posting this in the beta section is because avg and avast are being merged and is the next beat. Also, if you read through the forums, Avast borks the computer so bad that Windows cannot be logged into, even in safe mode, making uninstalling avast nearly impossible. This has happened to me as well. I had to completely reinstall windows because there was no way to uninstall avast, even in safe mode.
Thank you.
