You don't have to spend a lot of money on expensive software to block adult content on your computer. Most Internet browsers can do this for free. Blocking explicit content is important especially in a household where you have young kids and teenagers using the computer unchaperoned. If you want to unblock content, it's as simple as a few clicks for adults who would like the restrictions lifted while they browse the Internet.
Start from the desktop by clicking the "Start" menu and choosing "Control Panel." Select "User Accounts" to proceed.

Select "On" under the "Parental Controls" option.
Choose the websites and type of content you'd like to block, and save your changes.
Go under the Apple menu to find "System Preferences" and select "Parental Controls."
Determine the level of filtering you'd like. You will have the option to filter all content automatically, or choose which content you'd like to filter.
