Casey, I keep WinPatrol on all my PCs. It is small download, I have never had problem with it, and I don't think I have ever tried to stop a running application that it failed to stop. Once, sorta for test, I shut down Symantec Norton with it. It does not remove stuff, just keeps it from running. The basic is free, 30 dollar will get you membership (lifetime) to access an online database to identify whatever you find in your computer. Sometimes if you can stop these running processes, then you can get them to uninstall.
You can get it from WinPatrol.com, or CNet's Download.com . I am sure it won't hurt your computer.
