Ok, so I have no expience with networking or security... but, I could use some help. Please don't flame me for having no knowledge. I would normally just search and browse around, but I may not have enough time to get all the information I need.

I am a designer at a small company, I have been having a lot of problems with the network admin. (Personal issues) He has been spying on everyone, reading personal emails and whatever else he has been doing. Now he is trying to get me fired! He keeps playing games, blocking me out of parts of my computer that I have files which I need for work and just acting like a child.

The reason I am here, is I am going through the programs running in task manager and KiXtart was one of them. I'd just like to know exactly what he can do with this? Whats possible? and is there any way I can guard against anything he may be doing or planning on doing?

Any information or help would be greatly appreciated.
Thanks in advance.
