My workmate has been playing with various bits of software and has claimed that he has found a way to remote control my PC without my knowledge. We are on a Novell network and I have shut off all the remote services provided by Zenworks as well as the XP Remote Control software. I don't think he has had access to my machine to drop any cliet software on and have had a look just in case.

So, I suppose my question is this:

Is there any software that will run without asking my permission that would allow him to control or have a remote viewer on my machine?
