From the main console, click on “Internet & E-mail Controls”.
Click on “Protection Against Web Threats” and then click the “Settings” link. A new box will appear.
Be sure the box next to “Activate Protection Against Web Threats” is checked. TrendMicro recommends Medium as a default setting. This will provide protection against web threats without blocking most Web sites. You can set the Protection Strength to High, Medium or Low.
Choose what best suits your personal needs.
When finished, click OK.
