Hi, I am not an expert by any means, but I had the same exact problem on my sister's computer. After trying everything, the spyware (Windows XP Anti-Spyware 2011 (ya right)) kept on popping up no matter how much I killed it on task manager. My program was called "bda.exe", but Google sites stated that it can be any three random letters. After googling for hours, and going back and forth from rebooting in safe mode with no success, I think I found a solution. I downloaded a "file association fix for exe" for my windows. It is not an "exe", and this virus rewrites your exe files so that only it will pop up. You install that fix and it fixes your registry. Then you can run MBAM and any other virus or rootkill exe applications to get rid of the virus.
By the way, if your browser is also hijacked, you will have to download the "file association fix for exe" on another computer and then import it with a usb drive or on a home network shared folder.
I don't know if this is a new or improved virus, but it is incredibly annoying that it rewrites your browser and exe file association. I was about to send it off to a technician, but this helped me.
