HI, Since I have cleaned all the viruses, a "message box" like thing appears with an unrecognizable title and nothing or something written in very small letter, ex: windows\system32\mui\xpsp2res.dll at a random every time I press ctrl+alt+del before logging in to my computer. It also has an "OK" button only when entered leads me to the LogIn box, i.e to give the login name and password. I don't know why this appears all the time I try to login. Can anyone please help me clear this out. Thanks, Gopu.
