It does but you want to get a 3rd party firewall instead
of the windows firewall. WHy? Because windows firewall
only stops INCOMING traffic. It does nothing to monitor or
block any outgoing. Outgoing like worms, trojans, spyware,
viruses you already have or download(purposefully yet
unknowingly). By getting a thrid party firewall you can
not only monitor and block incoming but also outgoing. You
can also set up specific rules for programs. A free and
popular firewall is Zonealarm. Or you can spend money and
get a package like Nortons Internet Security that has a
firewall, antivirus, popup blocker and more. A firewall
is just one line of defense. Make sure you also have an
uptodate antivirus program you run regularly. Also make
sure you download critical updates from the windows update
site. And be a smart surfer.
