Hey, a quick question....its come to my attention that certain others who use my computer have been visiting sites that I do not wish them to acess (which has resulted in a significant amount of malware being downloaded) Now, I was wondering if any of you know of any Free programs that could be used to block acess to websites (preferably ones that would simply block all porn sites, and warez sites), and if possible one that operates discreetly. In addition If you know of any programs that can be used to lock individuals and folders on the computer I'd love to hear about em.
