I just updated Norton 2007 and installed Norton 2008, now Security Center
notifies me that I don't have anti-virus protection, but norton appears to be
operating correctly?
Norton also recommends turning off windows firewall? is this appropriate
Don't run two firewalls. You achieve no extra protection, you incur
the extra overhead of running two firewalls, and you run the risk
(probably small, but not zero) of conflicts between them.
See
http://www.microsoft.com/athome/security/protect/firewall.mspx
which includes the following:
"Q. Should I use both the built-in firewall and a software firewall
from a different company on my Windows XP computer?
"A. No. Running multiple software firewalls is unnecessary for typical
home computers, home networking, and small-business networking
scenarios. Using two firewalls on the same connection could cause
issues with connectivity to the Internet or other unexpected behavior.
One firewall, whether it is the Windows XP Internet Connection
Firewall or a different software firewall, can provide substantial
protection for your computer."
So choose one or the other, not both. Personally, I recommend keeping
the Windows firewall, and uninstalling the Norton one, as well as
everything else Norton. In my view, Norton is the worst security
software on the market.
