Win32/Virut has locked me down

My system has become crippled by the Win32/Virut virus, as well as several other trojan horse viruses (per AVG). During the download of an application upgrade, a pop-up came up that said the computer had been infected with a virus and asked if I wanted to fix it. In my haste, I clicked OK instead of closing the window. A new DOS window opened momentarily and listed a few .exe files that were loaded and that was it. The download of my upgrade never completed and the system froze. I rebooted and from my desktop I was unable to access any applications. I was told I didn't have permission. I rebooted in safe mode and ran a full system scan with AVG 7.5. It found over 900 instances of the Win32/Virut virus and many other Trojan Horse viruses. It began to repair the viruses, but when it reached 62%, it froze. I rebooted again and then was presented with my Windows Login screen...none of my account logins or administrative logins will work, not even to safe mode. I was reading, and going to follow a similar thread from this site, but now cannot get anywhere. What is my next step here? Thanks!

 

Virut affects the exe files so it's not likely you are going to get this installation to work. If you have important data it may be best to get a new hard drive for the machine. Format and reload the new drive and copy the data only from the old drive to the new one. I would not copy any of the exe files to the new drive.
