My daughter has become obsessed with Myspace and Facebook. She has to use her computer for her homework, so taking away the computer is not an option. I will unblock myspace and facebook as soon as she can prove to me that she can keep her grades up and and use the websites. Does anyone know of a way to block these websites on her computer. She has Windows Vista. We have tried to edit the host file, but it will not let me save it after editing. I do use the parental controls provided to block the sites, however she has found a way to bypass that as well. I have also blocked the websites in her internet options. Somehow she is bypassing these. Never underestimate the will of a teenager.
