Looking for survailence software..

Looking for some free software that can watch my pc why im away and see what others use it for.

Something that will record all internet history even when its deleted in the browser. And maybe take a few screenshots here and there.

Obviously its for my `own pc` and therefore i am breking no laws. But it does however need to be totally stealthed.

Thanks for help in advance.

 

I run windows Vista.

The people who have access to my computer are family members, i let them use my user account. I allready have spybot installed, along with my other malware software. The computer is mine, owned by me and no-one else.

Im trying to do some detective work, for personal reasons, if you put two and two together you will probably get an idea why.

Thanks for the advice and understandable people maybe a bit cautios to advise software like this. But this is what i seek only.

Thanks again, pls someone direct me to something !
