For a while now, AVG has identified a virus that it is unable to remove. The exact message is "Virus identified Win64/Patched.C" with "c:\Windows\System32\rpcss.dll" listed below it. I have run Malwarebytes Anti-Malware and SUPERAntiSpyware, but they have also been unable to remove the threat. It now seems like I can't even open Malwarebytes. My computer has been crashing at random intervals, and when I start it up, it tries to run a disc check that it is unable to complete. I am running Windows 7. Any help with this would be appreciated! Thanks!
