noitallmr – I think we have standard. It seems to block the bad things. But sometimes it’s annoying and blocks google.com because of open image/media. 🙁 Also if there is a video from youtube on a different site (like YWN) it just won’t show anything where the video is, which is kinda annoying but okay.
I just googled download K9 web protection and their site came up.
