I currently do use those two spyware programs,and occasionally find some stuff that gets thru.
Here is a typical scenario...I download a demo game, he plays it for a few weeks then doesn't like it or whatever the reason he doesn't play it so I uninstall it.Usually there is the program folder still there with nothing in it or some files.So I guess the question is, should I be concerned that stuff is still there or just forget about it and move on
