My 11 loves to game online, but is clueless about clicking on popups, if he thinks they look real. As a result, we recently had to reformat (was easier to reformat than to continue trying to debug it).
Immediately after reboot, I installed adaware, Ewido, and free-av. I also put in Kerio and Peer Guardian. Is this a reasonable amount of protection for him, or is there anything else I need to add?
