I have to admit that I got impatient and tried different things to fix this myself. Based on an earlier post to me, I downloaded ComboFix, but it didn't work either. By that time, I hadn't gotten any help from Norton, Uniblue, HiJackThis or Combo fix. The problems kept getting worse so I tried another antispyware application - Spyware Doctor from PCTools. I ran it and it identified 3 Trojans as well as other high risk spyware. It removed all the threats and the computer is running great now. I'm happy that I had a success story to share.
