[Thinkpad] OT: Cleaning up a home network

[Donald MacQueen]

A friend of mine asked me to come look at his home network. He has a 
cable connection coming into a desktop machine and then wireless 
connections from there. He said the gateway desktop runs very slowly.

He say that he runs Spysweeper, which I know nothing about, religiously. 
I plan to take a cd with SpyBot Search and Destroy as well as Ad-aware. 
What I don't have is a tool to allow me to easily identify what programs 
Task Manager says are running.

Any suggestions for my toolkit? Any other ideas about what to look for?

Thanks.

Donald
