Yeah, you've got something nasty on your system.  If Malwarebytes doesn't get it, get this program; Superantispyware

It takes out what most other programs don't anymore.  And has gotten plenty nasty off my system.  There is a free version, what i run.  My experience is though Spybot Search and Destroy is worthless anymore.  It picks up nothing.  It used to be about the best there was, but now--it no longer does the job it purports to do.  Malwarebytes is great and combine it with Superaintspyware and you get everything out there.
