Auto Computer Shutdown

Does anyone know how to set a time daily for ytour computer to shutdown all the way, or after a certain period of time without use?

I have a computer and people share it at home but always leave it on. I like to shutdown to clear all the mem etc and disconnect threats from the internet.

I use Windows XP Pro.

I am looking for a tweak or a program (free if possible!) that will do this.

Do a Search at PCworld .com or ZDnet.com. both of these sites do tests /reviews etc. They will warn for Adware in Free apps and their direct Downloads are clean.

I was looking something that would shutdown after so long, without activity.

Like a screensaver does.

That one looks ok, but wonder if tere are other, thanks though...
