I would take a moment to point out that, if you really just want to kill P2P software because of the spyware that often comes bundled, there are several good freeware programs out there that will do a very good job, and are well supported.
Lavasoft makes my personal favorite, Adaware. It's a little harder to find the free version on their site these days, but its there and I've been happy with it.
As for Process Killer, I don't entirely see the point for the same reasons as Cory.
As for WJView, it is a legit process, although it is sometimes running under the control of spyware. Look
here for more information.
