Not sure if this is the right forum for this but I figured more people would see it here than in one of the software forums.

Found this interesting spyware site by following a link in the Zen monthly newsletter http://www.freewebs.com/spyvsspyware/index.htm

Everything on there is freeware and there are some interesting goodies to have a play with. The guy who runs the site is a pc consultant who used these applications to sort out various spyware problems for customers.
