would like you to recommend a good FREE FIREWALL.  I HAVE XP2000.
THANK YOU

Zone Alarm from Zone Labs [www.zonelabs.com] is generally considered
the best free firewall software.

Try Outpost Firewall
http://www.agnitum.com/products/outpost/

I have been using AVG free edition from Grisoft for several years now,
it updates on a very regular basis however I understand it doesnt
synch very well with AOL ISP software.

And another option in the list is Kerio Personal Firewall (KPF).

www.kerio.com/kpf

I have tried ZAP.  I have yet to test/trial Outpost or AVG.
What I like about the Kerio developer is that s/he has a well
documented change log with frequent releases, good doc in PDF format,
and the capability to turn off certain functionality that might clash
with anti-virus or pop-up blockers one might already use (e.g.
g**gle's own toolbar with pop-up blocker).

The KPF initially installs as a fully functional FW for a free 30 day trial.
If not paid for within the trial it downgrades itself to a subset of
functionality that continues to operate smoothly as a free firewall.

Kerio is going to retire the Personal Firewall, so don't go for that.

I like Outpost Firewall as mentioned by peshkoff; along with Tiny
Personal Firewall. If you can tell me your use on the computer, I can
probably recommend the one that suits you the most. Zone Alarm is free
but it may slow down your system more so than other firewalls.

At the end of the day, what matters is the way you configure the
firewall. Really, that is what is comes down to... some people get so
annoyed with the firewall prompts that they changed settings to let
most of the traffic go unfiltered.

Do you have a router or the PC is directly connected to the cable modem/dsl... 
If it is directly connected, you really really need a firewall. If you
are gonna purchase a router , then purchase one with the built in
firewall. Hardware firewalls are much faster than a software one.

If i had to answer in one line, i would ask you to go for Tiny
Personal Firewall http://www.pcworld.com/downloads/file_description/0,fid,8051,00.asp

SYGATE - DON'T GO THEIR EEEP.

fii-ga,
I would highly recommend http://www.mcafee.com/us/ . In my opinion,
the best firewall system out there, a real must have for any computer
wishing to be safe. It's pretty cheap and is definitely worth the
money.
Thanks,

I would most definitley recommend Norton Personal Firewall

erm,i have been using Kaspersky  Pro version for a long time 
and u can download the un-locked version from some sites ..if u cant
find it ,i can help u.

Calling these firewalls is a misnomer as all they do is emulate some
firewall functions on a PC. As these firewalls are just another
process running under Windows they are just as susceptible to catching
viruses as any other process. There are certain viruses that
specifically target the firewall and switch it off together with any
AV software you might have.

The best solution is to run a stand alone firewall on read only media
that sits between your Windows computer and the Internet.
www.linksys.com offer a combined firewall/router that would be
suitable to your needs. It runs from firmware so is not susceptible to
the kind of hacks that are rampant on Windows. If you want to, you can
roll your own. Just get a defunct PC add two network cards and install
floppyfw a firewall solution that fits on a single floppy.
