From what I understand, that is a rootkit. Here are the two programs I would use to rid yourself of that. No need to install them, just download to the desktop, and double click the icon(s) to open the scanners.

Click the tdsskiller.exe link to download:

If TDSSkiller did not get it, then use GMER. Read the FAQ's at the bottom of the page to get a better understanding of the program before you use it:

I would also install, and run a FULL scan with MBAM, it's free:

Good luck.
