K9 Web Protection I just have to give a shout out to. If you are a parent who wants to control what your children are doing on the internet, or a worried wife,or just a guy who wants to make it impossible to get to bad website, this is for you.
K9 is the best web filter I have ever seen. It is finds bad sites, and it doesn't bother you about good ones. There are some things that I unblock,. like social networking, because I like facebook and twitter. Overall it is a really good experience.
The thing that makes K9 better than most is that it runs in the background of your computer without letting you know. This does two important things: one, doesn't annoy me, two makes it so that the web is controlled on anything. Some filters only work for one browser, but not K9, it will filter your web if you are using IE, Firefox, chrome, or even something like the web browser hidden in iTunes or something. It does not let you around. There is only one way out, the password (if you lose that, the email that you signed up with, so wives you sign up.) If you try to close the file running in the background, no internet will work till you restart your computer, so it does not let you go around it. (The only way I know how to get around it is use a different OS. This has been very tricky till recently when you can put Linux on a flash drive and just plug it in whenever you want to boot from it, convenient, but not cool for filtering.)
There are some other cool features too, like you can turn down your filter, but it will alway, no matter what, keep a history of all the sites you go to. Something else cool is restricting times when people can use the internet. I have a friend whose kid was staying up all night watching online videos, so she blocked it after midnight, problem solved.
The only down side to K9 is that it is only available for Windows and Mac, for most users that is awesome, Linux nerds need to find another way.
I just wish there was something like this for smart phones.
