The most common and well-known firewall is zonealarm. You can download or buy it at www.zonelabs.com
I would not recommend running two firewalls simuntaniously, never. If you are not pleased with zonealarm, or simply not interested, go with the norton firewall, since it will work well with your other norton products.
I am running Norton Internet Security on my Dell 4500,
desk top with WinXP sysytem and also the MS WIN SP2 has been updated to my system.
My question is this; what firewall should I run? The one provided by Norton I/S or the one from WinSP2, or would should I run both firewalls?
Thank you in advance for any help that is offered.
