Windows live family safety. Free download. Awesome monitoring and blocking, keeps logs of programs run, time spent, sites, etc. Best one imo
The program is for my parents who have absolutly no idea about computers, so it must be easy to use.
I installed Windows 7, and after trying to install a few older games I formatted and installed WinXP. The compatibility problems with many older programs on Win 7 is terrible, and until they've sorted it out I will be sticking with WinXP.
I had a look at K9, I will try downloading that. I will also try the above.
