I've heard a lot about his over the last few weeks, it appears there may be a new Hijack kid on the block. Saw a case of some poor Guy bein accused of slleping around with men cos his wife saw searches for Gay porn n HIV cures? You gotta pity him, cos the makers of IE would have you believe it's secure....IT'S NOT!!!!!!
You have probably downloaded software to 'update' your system from a dodgy site. torrent common. Have you joined any web 'broadcasting' sites lately? Or, Dare i say it, visited a normal everyday ...H..emm... Adult entertainment Site?
Either way, that discussion is for you to have with your wife later ( in case she doesn't believe you about the contents, sorry, but you could understand that she may not, cos if She didn't search., she's bound to think you have.) Judgement aside.
Switch off system restore.
Download or update AVG or other internet security software and allow it to do full system scan including partitioned drives, connected flash drives etc.
Check all ok
if this doesnt work, you may need to fully format your harddrive, a lot of work, but these things are VERY difficult to get rid of, and I can't help thinking that we're gonna see a lot more of this little beast. Hope the software guys pick up on it soon, before the divorce rate soars. LOL. Although, i can't help thinkin that thats what the litte B*******s are wantin for a laugh.
Hope this helps
