I had Norton 360, I used their uninstall tool to remove.
I did download Ad Aware before Avast, I used windows uninstaller for that. Might that cause the issue of freezing when dealing with administrative controls?
I'm almost 100% sure it's only when dealing with the admin controls (the popup that appears when changing or doing something that requires administrative privileges) as no matter what I do when that comes up, regardless of the cause of it, it freezes. Whether I ok or click no, press the x or even click something additional, it always freezes.
