I still don't see the harm in having both.
I see harm in advising people to get software firewalls instead (or
before) telling them (in order of priority):
1) get a nat router
2) update your computer via windowsupdate.com
3) if you don't need Java (ie Java VM, aka JRE) then uninstall
all versions of JRE/JVM (including MSJVM).
4) if you do need or use Java, then uninstall all old versions
and install the latest version from Sun. (note that even
if you update your Sun JRE, the install package DOES NOT
remove previous/old versions of JRE, and you will be vulnerable
to the bugs in those older versions while surfing the net).
5) obtain AdAware, Spybot SD, spyware blaster, and use them to
"harden" your installed browsers (IE and/or Firefox) with
their "immunize" function.
6) get a hosts file from the net and update it from time to
time.
7) Anti-virus software is last - and optional in my opinion. If
you're setting up a PC for a complete boob, then yes go ahead
and make sure it's linked to their e-mail client for scanning
incoming e-mail.
Software firewall is not even on my list.
Realistically, the use of Windows-98 vs any version of NT (ie 2k, XP,
etc) is actually step zero (0).
