Before starting a topic as suggested by xBlindx, there were indications of a backdoor and also the virut file infector in the Malwarebytes Anti-Malware
Warning on backdoors:Backdoor ThreatIMPORTANT NOTE
: Unfortunatly One or more of the identified infections is a backdoor trojan
This allows hackers to remotely control your computer, steal critical system information
and download and execute files
I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.
Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS.

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.
Virut is a file infector, from you previous posts you said that you have ran the AVG w32/virut removal tool? Correct? Nevertheless this infection is very nasty but it doesn't appear to be active at the moment, either because it was leftovers or simply just it wasn't installed completely.
I would still recommend you format the computer and backup any data information as needed. No exectuables, since this computer was compromised.NOTE:
