How to Block a Website in Internet Explorer 9

Many people use my compute to surf in the Internet. However, I don't want them to open some specific websites. Could I block those websites in IE9 so that others who use my computer can't open without my permission.

Solution

Using IE's content advisor to block certain website.

1. Open your IE browser. Click on "Tools" which looks like a gear, and then select "Internet options".
   
2. In the "Internet Options" window, select "Content" tab, and then click on "Enable" button under "Content Advisor" section.
   
3. Select "Approved Sites" in the "Content Advisor" window. Type a website which you want to block in the box under "Allow this website". For example, I enter "www.facebook.com".
   
   Then click "Never" button to disable this website. You will see this website added in the list.
   
4. Click "Apply" button in the bottom of the window. If you want to use a password to protect it, you select "General" tab and check the box next to "Supervisor can type a password to allow users to view restricted content". Then click "OK" button to close this window.
   
5. Now you will see a new window which let you enter password. Type your password and hint, and then click "OK" button to close this window.
   
6. Now open the Website which you block before through IE9, and then you will see a window that ask you to enter the password. If you want to view this website again, you should enter password, or you could not open it.
