Judging from the name, I'd say this got installed by kaZaa, but I'm not sure. Near as I can determine this file is created from scratch whenever the computer boots, as I cannot find it in the system anywhere. It runs like seti@home, eating up allof the computer's resources and doing constant online activity. It could be a remote control attack program for all I know.
It even tries to close task manager when you attempt to find it and close it down. every time I boot this computer It takes several attempts to get this program located and the process tree shut down. Whenever the computer goes into screen saver mode it respawns.
I will be wiping and reloading this computer from scratch later today.
