Greetings --
WinXP's built-in firewall is fine at stopping incoming attacks, and
hiding your ports from probes. It doesn't give you any alarms to tell
you that it is working, though. What WinXP also does not do, is
protect you from any Trojans or spyware that you might download and
install inadvertently. It doesn't monitor out-going traffic at all,
much less block (or at least ask you about) the bad or the
questionable out-going packets.
ZoneAlarm, Kerio, or Sygate are all much better than WinXP's
built-in firewall, and are much more easily configured, and there are
free versions of each readily available. Even Symantec's Norton
Personal Firewall is superior by far, although it does take a heavier
toll of system performance then do ZoneAlarm or Sygate. It's been
several years since I've been tempted to try McAfee products. Their
quality seemed to take a steep nose-dive after they were acquired by
Network Associates.
No, you shouldn't run both firewalls. Running two or more
software firewalls simultaneously is unnecessary and can sometimes
cause conflicts, possibly negating the
protection of both. In any event, having two firewalls running
simultaneously is most certainly an unnecessary drain on system
resources.
