OpenDNS.com
I did not see any mention of OpenDNS (or a similar service) on your generally excellent security thread. In my opinion, it is one of the cornerstones of keeping a system safe from threats when you have "non-sophisticated" users on your system(s). Nothing can wreck a security arrangement as fast as a curious 14 or 15 year old.
Opendns is a FREE service (you can pay for "more", but the free version is excellent) that serves domain names instead of using the default DNS for your 'net provider. By setting a few quick and easy options, you can block various sites that you don't want visited. Once they ID a malware site they will block it, then if you click on it, it won't go there and you get a warning instead. So, when the "problem user" clicks on a link to a malware infested site that promises game cheats for his favorite game, opendns prevents the damage he would otherwise have caused.
We have desktops, laptops and a wii plugged into the internet. Opendns is on our router and protects all of the above by controlling what sites can be visited.
