My brother had this on his laptop - something must have been downloadable on it as it hijacked his laptop, I had to reformat the damn thing for him - he had no firewall, no AV software, no spyware software on the lappy. Needless to say when it went back to him it was loaded up with all sorts of protection. If I could of found a condom to fit it, it would have been wearing one of those too.
Was the hijacker called spyware Quake?
I can't remember what it was called, I tried for hours to sort it out without a reformat, but in the end lost my rag and just reformatted it anyway - serves him right for going on dodgy sites!
