I use NAV 2004 which is different. I was not aware the NAV 2005 turns off the Window's Firewall if you turn on the worm blocking. I would think there would be an option SOMEWHERE in NAV that would allow both but without having that program I can't check it. I can not guarantee that the Firewall is going to block all worms but it will block other things that the worm blocker in NAV does NOT block. IF you can not use both, I would choose the Windows Firewall but like I said, I would really think that you would be able to use both. With NAV 2004 which does NOT have a worm blocker as aggressive as NAV 2005 does and using Windows Firewall, I have never had a worm problem of any kind. I realize that I'm not answering your question completely but with the program in front of me I can't give you a complete answer, Sorry. Maybe somebody else uses both programs can give you a definate answer.
Dell Dimension 4700, Pentium 4, 2.80 GHZ, 80
ATA Hard Drive, 512MB, Windows XP Home Sp2. You have discussed this before but it didn't really answer my question. I am asking you because I know you use Norton AntiVirus and Windows firewall. In Norton 2005 AntiVirus it has Internet Worm Protection which when you install automatically turns off the windows firewall. Under the exception in the windows firewall I can find live update but the worm thing you can't put. I ran a security scan at Shields-up and with the Windows XP firewall all were stealth and passed. With the worn protection on and windows firewall off it showed failed- all stealth except ping. To make a long story shorter with the worm protection off will I still be protected from worms. Thank you for reading this long post after you have already said the worm is not a firewall. Thank you again.
