My friend has a older Dell that runs XP. His anti virus was about to expire and I said, hey don't spend money, get avast. When the removed McAfee he started getting these popups: He successfully installed ad-aware and avast and he still gets these popups. Basically every time he opens a folder or does anything the popups resume. I haven't been over (he lives 40m away) to see this in person and I tried to coach him over the phone, but so far we had no luck. Any drastic steps that I need to get here? Should I just say, dude your computer is old, time to get win7? Is there something I should try that I haven't thought of yet?
