If antivigear gets on your computer you will go crazy trying to get it off. You can delete, uninstall, anything you will do will not work. It is there popping up in front of you for the rest of your life. Or your computers life. Is this sort of problem what Hijack This is for?

Think thats probably malware, best method would be Hijackthis Log

so AVG you recommend?

Sure-- I've used it for years.Never a problem

so im guessing the avgfree would be the basic version? all it includes is antivirus nothing else.. if this is what u have ad never had a problem ill go with that one but if you have somthing else.. lemme know please.
AVG Free Advisor - Free antivirus and anti-spyware downloads

I like AVG as well although I got the paid version and I also got their antspyware ..
But NOD32 is the best out there so many years running but you pay for the best.
And spyware doctor is the best anti spyware app IMO
