I have picked up a redirect virus that i can't seem to get rid of. I use IE8 and Windows XP pro, running dsl thru bellsouth(att). I have run sysmantec, ad-aware, MBAM, and maybe a few others. In regular and safe mode. Combofix runs thru level 50 the crashes the computer. I have also reset my modem to see if it was infected. What step should I take now? I can start from scratch and post logs if you need me to.
