Hi, ewido found Not-A-Virus.Exploit.HTML, riskhigh, and ignored it. It also found Hijacker.Agent.a, risk high, and tried to quarantine it but it says "error while quarintining." There's also Heuristic.Win32.Dialer, risk medium, and it ignored that. Then there's a bunch of trackingcookies, risk medium, which it deleted.

I deleted my cache, saved forms, history, cookies, temp files on both IE and Firefox and did disk cleanup. I also ran Spybot, Adaware, and Avast. What else should I do?

Please help a noob.

On Ewido which version do you have? Ewido or the AVG 7.5 one? And un ignore the things you did ignore and re scan. When it picks them up dont quarantine just DELETE.
Good Luck,
Nick
