With the Internet rife with pornography and violence, many parents rely on software to block those sites from their children.
Consumer Reports just tested eleven programs to see how well they shut out offensive web sites.
The hunts, like half of all internet-connected families with teenagers have special filtering software to block offensive sites.
Consumer Reports Dean Gallea tested 11 software programs to see how well they block offensive sites.
Some come free with a subscription to AOL or MSN. Others like Net Nanny and Norton Internet security cost between 35 and 70 dollars.
The programs offer different levels of protection for various age groups. Consumer Reports checked the settings for young teen.
Nine of the 11 programs didn't block a site that tells you "how to kill someone with your bare hands."
And a continuing problem, some also blocked a lot of legitimate sites like the national institute on drug abuse, as well as the southern poverty law center.
We did find some products that were better striking a balance between blocking the objectionable web sites and letting through the informational ones.
Top ratings went to a program called safe eyes, which you can download for 50 dollars.
But no matter which filtering software you use, Consumer Reports says do what the hunts do and keep the computer in a family so you can keep tabs on online activity.
