Kids Using Computer
If your tech-savvy kids are spending a fair amount of their computer time surfing the Internet, there’s a chance that they may sometimes accidentally stumble upon adult sites that you would definitely not like them to see.
Keep your Kids from Seeing Adult Content on the Web
It is nearly impossible for any parent to manually monitor their child’s entire computer session and what you therefore need is a solution that works in the background even while you aren’t around to watch over them.
There are couple of options. For instance, YouTube has a safety mode to block videos that aren’t appropriate for children. Then you have OpenDNS that you can configure with your router or computer to block an entire category of websites that contain violent or adult content.
There are some site blocking programs (NetNanny for example) that monitor your kid’s activity on the computer and will automatically restrict them from visiting sites that aren’t meant for them. Then you have the slightly-geeky 127.0.0.1 trick to that helps you block any of the known websites on your computer.

FamilyShield is part of the previously described OpenDNS service but the advantage here is that you don’t have to do any tweaking to block adult content – just change your DNS server entries (these are different from the original OpenDNS values) and the web filters are immediately activated.
If you chose to setup FamilyShield on your router, sites that contain adult content will automatically get blocked on all your computers, gaming consoles and even mobile phones that are part of your home network. It even blocks proxy sites that are commonly used bypass the web filters.
Website Blocked
It can’t get easier than this and there’s no software to install though your kids are likely to encounter ads when a site they’re trying to visit gets blocked – that’s the business model of OpenDNS.
