Norton; firewall is many times more effective than Microsoft's. MS firewall
is inbound only, while NPF is inbound and outbound. Plus, the NPF has
intrusion detection built in, and a feature that will turn itself back on if
you turn it off to play an online game and forget to turn it back on. NPF
is much more configurable than is MS, and uses a common interface with NAV.
The firewall from MS is a very weak form of protection. You are much
better off getting the NPF.
