About a year ago we were told about K9 Web Protection and we love it. It is so easy to install, it's free and it is very, very user friendly. K9 is a program that monitors your internet use. You are able to go on and tell it what categories you want blocked and if one of those comes up you have to enter a password to be able to see that web page. It is a free download. It was created for Parents to help protect their children from harmful information on the internet. Their website gives parents other ideas on how to help protect their children from the harmful effects of the internet. But we love it for us even though doesn't use the computer yet because it helps keeps those "pop up" accidents from happening. :)
On top of blocking websites, it records EVERY single website that you go to or Every pop up window that comes up so that if something does get past the system it is recorded. It tells you the time and date that it was viewed. We wanted to recommend this program to all of our friends and family as a way to protect their families.
