the biggest threat apart from virus attack to windows based systen isI would suggest getting some.
I don't know about your router, but they can be pretty good
protection from the outside. However, some malware comes
in because it is invited in.
Sorry, all I can do is offer the opinion of a simple home user.
No, a router is not enough. But there are routers with additional
functions that can provide *nearly* enough protection. The XP
machines should have additional AV software so that you can
detect known malicious content that was invited in. Some kinds
of malware have web based attacks - the browsing ability of the
XP machines opens that possible vector up.
Not being a network guru myself, I suggest that someone with
more knowledge in that area advise you.
If nobody jumps in here, I suggest that you start another thread
with this query.
posed by internet explorer...you can have firewalls, routers,
antivirus as much as you want but it will not protect your operating
system from attack by malware and spyware invited in by this secruity
nightmare part of windows...not using windows for email is ok except
that virii may travel the network looking for windows boxes....its
like closing your eyes when someone throws a punch and hoping it wont
hit you....i would advise using mozilla firefox as you browser and
deleting shortcuts to iexplorer so it is not easy to get to...it is a
part of windows and cannot be got rid of unless you use a prduct like
XPlite so the starter file is there if you have to use it
