Newer versions of Windows also feature an updated, improved version of Windows firewall than prior versions of Windows. If you scan clean for malware, don't want/need the additional features of a third- party firewall, and are a relatively low risk user, then the Windows firewall.
Most simple two- way firewalls ask you to allow or deny Internet access for unknown programs. Many also automatically allow trustworthy apps and remember your decisions to become silent over time. However, these software require additional configuration of settings, especially at the outset. The initial firewall that came with XP was simple, and only allowed protection from incoming traffic, by blocking any incoming connections not initiated by your computer.
