If you’re using the built-in firewall that comes with Windows XP, you might want to consider using a different one. Windows XP’s built-in firewall is not bad but it doesn’t have configurable outbound protection. Comodo Firewall Pro is a good alternative to the one that comes with XP. It’s also free.

Comodo’s wizard’s will help inexperienced users with configuring their security settings. Experienced users can fine tune the settings and check their firewall’s security settings by using Comodo’s online vulnerability scanner. Popups let you know of any important events.

If you don’t have a lot of experience with configuring personal firewalls, check out the documentation and faq.

How many of you are using a different firewall than the one that comes with Windows?
