An anonymous reader writes "I have two kids, 7 and 8. I would love to allow them internet access on a regular basis. The problem is what's out there: I really don't want them to deal with porn ads and such, but making either a blacklist or a whitelist myself would take months. So I figured I would ask you: what free software would you use with preferably prebuilt lists to protect your kids online? What is out there with fairly easy configuration ability (to allow for game servers — they love Minecraft), but secure enough they can't just bypass it using a Google search?"
