Opinions needed really...
Me being extremely paranoid and due to my computer going through a severe allergic reaction last year to different software firewalls, I got a router, just for the firewall.
I also have Norton Internet Security.
Do I need both or is the router and a AV program fine?
(Please don't get into a Norton bashing thread, this is not what it's about. Pretend it's a brand X Firewall.
)
Probably the thing I would miss is the "productivity control" on NIS, as I have a user account set up for my nephew and it gives a bit of control.
