i would suggest to go to this link http://www.bitdefender.com/scan8/ie.html

it's an online antivirus scaner. maybe it would help you. because usually viruses can disable the antivirus detection but with online scaner there is nothing to disable because there is just a plugin and no .exe file that he can infect. You can give it a try.
