firewall

[@@]

Hello:
PC and communication system  I have consist of:
 Router build -in  firewall - antivirus build -in a firewall and firewall in Windows 7
I believe that this is too much: What is the best way to choose a firewall. In other words what a firewall, which I do and what is the one who stopped him
And if all were employed. What is the result of this

I really can't figure out what your asking..  Generally however, if you're on a home network with only a few TRUSTED users/computers, then Windows/third party firewalls aren't necessary because the router will act as a hardware firewall, protecting your from the Internet..

If you're on a network with a bunch of people in a business, it would be good to keep at least Windows Firewall enabled or a third party firewall, to protect computers inside the network, from other computers/users.  A hardware firewall in this situation would protect ALL users on the network...

If Vista is the OS being used, then the Vista firewall would be good as it is "double-sided", preventing outgoing and incoming malware.  Windows XP provides only a single sided firewall, blocking only incoming traffic.  If XP is being used, a third party firewall might be better, one that has double-sided capabilities..

I wouldn't use more than one software firewall, what ever you decide to do..

Thank

This means I can stop the firewall for antivirus (Kasparsky Internet Security)

You should use one software firewall in addition to the router's NAT. It's your choice whether it's the one built into Windows or KIS (though KIS is a superb program). Either way, do not disable your anti-virus.

Is there a relationship between the speed of browsing and firewall

I've heard anecdotal stories about some (especially Zone Alarm) but no, there should be no noticeable difference.
