I got something like that a few weeks ago, I was able to get my antivirus to actually kill it by ending all processes on the task manager that didn't look normal, and then running my antivirus/ad-aware. Been fine since. If I ran the antivirus stuff without stopping the processes it would delete what I suspect were subsidiary virus files but not the main file that would recreate the subsidiaries every time the software deleted/quarantined them.
