I have a user who has contracted some sort of trojan. Looks like it modifies defender.exe, and runs a program called "Spyware protection, Designed to protect" and gives the same garbage not letting me open just about anything, saying my computer is infected. I've run malwarebytes anti-malware on it in safe mode, found something, removed it, but it is still there. I even attached the HD to another computer and ran MBAM on the entire drive and nothing. A system restore seems to have put a band-aid on the problem. Symantec sees that defender is causing problems, but does not detect the virus. any suggestions?
