This page will help you to access free Personal Firewalls which you may use in place of the firewall included in Windows XP or you may wish to add to a Win9x/ME product. Again some of these are no longer designed to run with older operating systems and you may have to search further to find one that is compatible. I will provide a link in the Computer Help Links on this site that will provide a few more possible Firewalls for your use.
Zone Alarm
Comodo
Omniquad
SensiveGuard
