Try also anti injection program, just in case. There is also good way to do a virus or troian scan in Save mod (F8). Hope this is also helps ;)

Rifleman, that is useful - didn't know about that one. I use XPL's Linkscanner Pro meself, because it actually stops stuff coming down, not only gives you guidance when you are browsing. There is a version of that included in AVG's free AV 8.0, but the standalone Linkscanner that I use you have to pay for - worth it to avoid all the sort of hassle fakeware gives you though :)

You need something like XPL, or WOT or Mcafee Advisor because you cannot otherwise know about these invisible threats until it is too late and you have something you do not want already parked on your drive..
