Edit VIRUS FREE!

I had the same problem, a program called security defender that tried to pretend to be windows defender (even had the same icon, creepy) and gave me a bunch of warning sirens saying my compyter is infected and I would have to pay for them to remove the threats. this worked for me: http://download.cnet.com/Malwarebyte...-10804572.html
