Okay, before shouting Adaware, Spybot etc. - I've tried them.
Yesterday on my work computer I got blitzed with pop-ups. COuld be something to do with a was engaging in some downloads and inadvertently gave permission to an ad company.
We've figured out that the pop-ups are related to an online site called 680180, or something similar.
Spybot doesn't do squat, nor the others. Something obviously got installed, and now I can't use IE without getting bombarded. Hence, I'm reaching you via Mozilla Firefox.
Any ideas?
