You can block the ports used by whatever package he's using. You can also disable Remote Desktop. Right click on My Computer, Properties, Remote, disable Remote Desktop at the bottom of the screen.

Follow johnwill's advice, and uncheck Remote Assistance on the same window where you unchecked Remote Desktop. Turn on the Windows firewall, go to the Exceptions tab, and make sure you uncheck where it says Remote Desktop and also Remote Assistance.

It's also possible that he is using a VNC program

There's two ways he could be doing this:

1. He got onto your computer and installed a VNC Server onto your computer
or
2. He's using a VNC program that doesn't require the installation of a VNC server (ex: GenControl, we use it at work)

To solve this for each probability:
1. Go into the task manager and look for any processes that have VNC in them (ex: winvnc)

2. Uhh, try the one for 1. and if fails try blocking access to some of your ports i would recommend ports 5800 and 5900 (that's what UltraVNC uses at least). You should try do a netstat -a -b in command prompt to find what processes are listening and what ports

Another solution would be to just smack the guy in the back of the head... Put small mirrors in his CD drive, put magnets in his floppy drive and on top of his hard drive... lol

No i'm just kidding i am in no way soliciting the acts..blablabla

Just try 1 & 2 and get back to us

I'd also just confront him and find out what he's using. It's certainly possible to block it, but we have to know what it is.

A HijackThis log would be useful to see if something you don't know about is running...
