Cyber Sitter is probably the best. It is sends you an e-mail everytime your child goes on somethine suspicious. It also takes pictures and records EVERY website your child’s been on. You can also use it to restrict internet access at certain times of the day, and you can also restrict your child from using IM services. Unless your child is known for computer hacking (highly unlikeable) it is nearly impossible for your child to figure out how to disable Cyber Sitter.
