HiJackThis is the program used at the site I linked above, both for submitting logs for analysis and for repairs for this problem.

I'll note that instructions that the analyst provided there required some specific selections, based on the logfiles, to enable HiJackThis to get the job done. Additional file deletion and clearing of temp data was also included in the fix.

Several other sites that had less helpful info noted that just running HijackThis (and/or AdAware or Spybot) is unlikely even to detect the problem, since it's an installed program that you gave permission to put on your machine. You probably didn't know you gave permission, and likely didn't intend to; but your crud detectors were told that it was intentionally installed, so until you figure out how to tell them otherwise - it ain't spyware to them.
