Here's the deal. I end up having to re-install my grandfathers computer every 6 months or so. He can't see very well so he goes clicking everywhich button. I'll be damned at some of the stuff that ends up on his computer - and ends up missing from it - and things his computer ends up doing (like incurring a $250+ phone bill via dial-up). I figure I will just make the default user a Guest account which I believe should help, but I don't know a ton about permissions and such. If anyone would care to enlighten me on some helpful settings or even a unabtrusive top notch program that can help to protect the computer from unwanted user actions, that would be appreciated. I've already got him on a good free anti-virus and convinced him to buy a copy of admuncher if & when it goes on discount again. So the internet part is taken care of fine. TIA.
