I agree Metcaff. Running your Ad-ware SE by Lavasoft or HighJackThis spyware and addware scanners along with ClamWind or AVG antivirus and frequent defrag and chkdisc..is good housekeeping, but this computer is obviously not functioning properly, MS relation to this is they wrote the OS, I stated my opinion to help someone and it was not you...If you have a problem with MicroSoft, take it up with them. I was not talking to you...I have for many yrs built, building, installing software and hardware, troubleshooting computers, so I need not justify my credentials. I know this z prob not just a trojan, sounds like a virus that started with the IE and still going...I could be wrong.
