Infected with XP Anti-Spyware 2011

Hi, somehow my PC has been infected with XP Anti-Spyware 2011. It appears to be a Windows program, but I know it is not. I cannot run TDSSKiller, Mbam, TFC or anything else. Every time I do, the pop ups start or the process I want doesn't run. Can you help me?

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.

Thank you aquavirus for your suggestions. I did a little research on the file association fix for .exe as you suggested. I read some information at PCPowerGuide.com about the file fix. I did not edited the registry by myself, but performed the very basic step of creating a new file extension for the .exe. The information reported back that "ryg" (the malware) was the program that opened the .exe extension. I also enabled dumping the page file before shut down. It has been a couple of days since then and I am happily reporting that my system is back to normal. I was able to complete a virus scan which found 2 other problems. Thank you so much for your help!!!
