Norton is total crap. If you talk with any computer guru, coder/hacker etc... they will all tell you not to use Norton because its totally junk. And thats with any of Nortons products.
Good Products:
Firewall go with: Outpost Personal Firewall
Anti-virus go with: Avast---Its great and its free.
There's nothing wrong with Norton; although they sold out to Symantec and haven't used the Norton name much anymore. Every company I worked for except one has used Norton/Symantec AV products.
Cisco 501 which I used to have at home, Netscreen 5XT which we have at work....there's a bunch of good firewall boxes around $500. At the low end ($100-150) the Linksys and Netgear dsl/cable routers are still good enough to keep 99% out and more easily configured.
