I have been hit with the anti virus security pro virus and have tried to remove it using your excellent guide. I have used this guide peviously on another virus and it has been successful. However this time when I start the PC in safe mode with networking instead of going into windows it is now opening a box which is titled cmd.exe. Within this box is the prompt c:\Windows\system32> with a flashing cursor. I am unsure as to the next step as I am not sure if this is a valid windows screen or a fake screen introduced by the virus.
I have turned the computer off and restarted to try and get it to go into windows to run your other suggested method of opening in safe mode but the same cmd.exe box is coming up. My computer is running on Windows 7. Any help or advice would be gratefully received.
