While Norton sorts out their problems, you may be interested in checking out a couple of (free) alternatives for web filtering:
OpenDNS Family Shield http://www.opendns.com/home-solutions/parental-controls - easy to set up, covers all devices connected to your WiFi
Blue Coat K9 Web Protection http://www1.k9webprotection.com/ - works on PCs mainly
Neither is as full-featured as Norton Family but they are good alternatives (or even additions)
