Recently, I purchased a Linksys router to provide multiple pc's access to my internet connection. When I bought my router, Linksys states that a 3rd party firewall is not needed, but a friend informed me that she was watching The Screen Savers, and they said, according to Linksys, that their routers and Zone Alarm compliment each other; and also provide the user with a double firewall.

Before I install Zone Alarm on my pc, I was hoping that some of you would provide me with some feedback about that? What would you do? Is this necessary? Thank you.
