Bad Virus

I cannot run .exe files on a PC. It keeps saying there is no file association on exe files. Well I got in windows explorer and setup a file association EXE --> application just like my laptop. Still no dice since i cannot open .exe. i cant do anything open command promt registry or even restor to old point or run any virus scan software. Anyone hear of this?

Have you tried running an web-based Anti Virus program to see if you are infected?
