Mr. C- More help needed

Recommended Posts

You assisted me last weekend with a Trojan removal and now McAfee, Microsoft Security Scanner, and Microsoft malicious software removal have found a new Trojan - Medfos. Both of the microsoft products say they partially removed it. I tried to find the file to delete, but I can't find it.

I ran malwarebytes anti-rootkit twice and it didn't find it, nor did regular malwarebytes.

I also ran roguekiller in between running mbam.

I would appreciate your assistance again.
