Be aware, I am not from the staff or other authorized person to give you advices here.
I am answering to you only because I had the same problem, even put a question in this forum, and got no answer so far. Fortunately I have asked in another place too and find out it is a ZeroAccess virus.
I made some investigations and here is what I did:
-I have used Hitman Pro and Gmer; after that I was able again to run an antivirus (before that, all of them closed unexpected or stopped) - this stopped that exe process from Task Manager, with many numbers.
-I have installed a free antivirus and scan with this
-I have run the TDSS Killer (be careful, I think I read a warning here in this forum about using TDSS Killer)
-I made a scan with AntiZeroAccess from Webroot, and this told me "your system is not infected by ZeroAccess/Max++ Rootkit!"
Please be adviced, this is only how I get rid of the same kind of virus.
