Later on if you want to disable that feature, then on Step No.4 just press the button named- Disable or if you want to add some other sites in your settings then chose the button labelled Settings... That's it...
1.If your children (or any other Internet browser in your home) feel that their Internet options are being limited, spend some time reminding them what happens to computers that are completely unprotected, and present the Internet filter as just another part of a good security setup.
2.Restricting a child's web usage when they are used to unrestricted access may result in negative behavior. Try to to install an Internet filter at an early stage to get them used to it.
3.Content Adviser only filters Internet Explorer, so if a family member installs another web browser such as Firefox, filtering will not be effective. To prevent a user installing another browser (such as Firefox) and bypassing Internet Explorer's filtering, create another User on your computer, and assign it limited user powers. Get the other users to log in using the new user ID, and their ability to install new programs is restricted.
4.Resourceful children may try to use "hacks" to bypass your controls:
* Free proxy service websites (search on Google for "free web proxy") can hide further webpage browsing from parental controls. Most parental control software will automatically block access to these sites, but check out History logs to view any attempts, and talk to your child to generate agreement on what surfing is acceptable.
* If the child logs in to the computer using an administrator account, they may attempt to turn off Content Adviser by deleting registry settings. Create for them a new account (with limited powers) to restrict their ability to edit the registry.
