Protecting children from harmful material on internet

As for me and my kids, I am using the Firefly Web browser. It is a Web Browser made specifically for kids to make their surf experience safe. Firefly is meant to be SIMPLE. We know there are lots of complicated software tools for making your surfing safer. We believe parents should be active in their children's online experiences. Once you have your favorites entered, parents should be able to let their children surf safely without constant supervision. However, Firefly does not disable or prevent children from using chat or other web-browsers. It is up to parents to make and monitor their household surfing rules, one of the simple rules for your children is simply to use Firefly to surf the net.

What you can do is use some password in your PC so that they will only use when you open it through your secure login, in that way you can always check later what they have done. I have seen recenly something cam in the market hich can spy on the children use of internet.

You could use a firewall like zone alarm and keep the parental control button on - so that they can not access any adult or bad sites.
