Thank you for taking the time to answer my post. Please bear with my long
version as its important to me that whoever answers this understand a unique
situation I have with the way I use my computer.
I've always used a simple dialup for my on line work and have not had any
virus issues at all using the EZAntiVirus from CA that I have installed.
Along with this, I use the XP in-house firewall. This combo has worked for
several years.
My situation is unique as I need my system as free of 3rd party software as
possible for the testing I do for developers producing add on software for
the Microsoft Flight Simulator program.
This being said, I have just signed up with RCN for their broadband cable.
This of course will change my on line scenario, as the port will now be open
all the time the system is on.
What I need to know is this;
RCN offers free Mcafee software and my experience with Mcafee is that it is
invasive to the registry and slows my system, which is not the best thing
when you need every once of performance for testing.
Will my present combination of AV and using the XP firewall be sufficient to
protect the system with the new broadband in operation or will I need to
make changes in the way I protect the computer?
Many thanks for any and all information.
Dudley

Use a Cable/DSL Router such as the Linksys BEFSR41 or a more comprehensive
Router that has a
Full FireWall implementation.

This will greatly diminish the threat of Internet hackers and Internet worms
from reaching
your computer.

There are many other advantages to using such a device as well.

As always, I suggest specifically blocking both TCP and UDP ports 135 ~ 139 and
445 on *any*
SOHO Router.

If you use a router for your broadband connection, you can also
set up the router's own firewall, they use to be quite powefull and you wont
need to spend extra money.

You will of course need to ask your ISP / Vendor, but normally you can
access the settings from a browser logging in to http://192.168.1.1

Regards ;)

Use a hardware firewall as David Lipman suggested. The Linksys WRT54GL is a
good one, but not the WRT54G. Look at articles on www.tomshardware.com
about the various firewalls. Hook your multiple computers together using a
gigabit router and have it hook to the firewall router hooked to the
cable/DSL modem. This will give you the capability of having gigabit
transfers between computers and an easy way to disconnect all computers from
the internet during testing. Do not run a anti-virus on test systems unless
you are checking interactions between the AV and your software/hardware. If
you have a larger facility with many computers, then you need a dedicated
firewall from Sonic, Pix, etc. The better ones permit multiple broadband
connections so you can maintain connectivity when one goes down.

Since your are just writing game plugins, you probably don't need internet
access on the test systems. You can assign them a fixed IP address block
that is prohibited from using the internet via your firewall. Just a few
ideas. Remember a new system without a firewall connected to the internet
will be compromised in 2 minutes or less if you use Windows. Sometimes on a
minor ISP you might get a half hour or so, but most of the attackers know
which IP blocks are for broadband providers. Many years ago, it would take
about half an hour to see an attack when I had dialup.
