I have a member of my household who repeatedly checks out porn sites on our computer?

I have threatened to disable the computer when I am not around-we have had malicious viruses because of this. I have talked to him over and over about how viruses can destroy your computer, but he chooses to ignore the threats. Luckily our anti-virus protection takes care of these. However, I would like to somehow, lock him out of the computer when I am not home. We have 3 user screens on the computer...his, mine and the main. What do I have to do to accomplish this? Part of the computer components were a gift from my brother, and the rest was, either purchased by me, or given to me by close friends. I do not want him to ruin the computer by his carelessness and ignorance! Please Help!!!

Simply activate Parental Control in your browser or Install Net Nanny on your computer. These provide you with an option of password protecting the illegal content that the member is viewing. You are also advised to instal Mcafee's Site Advisor which marks dangerous sites with a red flag. This might scare the member and would avoid viewing those websites.
