The security zone "Restricted" has been selected. Any sites that should be treated with the highest level of security can be added here by clicking the button "Sites..." The URL for the site has to be added manually as shown in the figure below.

In the figure, the advertiser Doubleclick has been put in the restricted zone. Note the use of a wildcard * in the URL. This provides for the many variations on sites from the domain doubleclick.net.

To enter an URL type it in the indicated space and click "Add". Entering sites can become tedious and there are Registry files available on the Internet for automatically creating substantial lists. These lists, however, contain the personal biases of the authors and may not always agree with your own choices. In general, the entries are advertising agencies and porn sites.

To close the box, click the "OK" button at the bottom.
