Should You Use Windows Firewall In Conjunction With a 3rd-Party Firewall?
Again, I would say the answer to this is "no". Personal firewalls sometimes require a significant amount of tweaking and configuration to make them as secure as possible without impacting your ability to communicate on the network or use the programs you wish to use the way you need to use them. Adding a second firewall on the same system can greatly confuse things and make it exceptionally difficult to determine where any connection problems might lie or what you need to change to make it work.
I am not networked to any other computers.
I use my computer primarily for email...occasionally surf the web.
I have DSL and my computer stays on 24/7.
My server has a firewall.
My router has a firewall.
Windows XP firewall is turned on.
Do I really need a third party firewall?
I've used several in the past (Zone Alarm, McAfee, AVG) and none of them have ever "caught" anything. All they seem to do is take up a lot of resources, especially McAfee.
Shields Up says my computer is secure.
I don't quite understand. If my incoming is completely secure, why should I be concerned with outgoing?
