ZoneAlarm: The World’s Best Free Firewall

For the best protection, get this firewall, which is far superior to XP’s Windows Firewall and keeps you safe from Trojan horses and other dangers.

The Windows Firewall that ships with XP has one very serious deficiency: it can’t monitor and block outbound traffic from your PC to the Internet. Many Trojan horses do their damage by installing themselves on your system and then allowing others to take control of your PC, or by using your PC to attack web sites, servers, and other computers. The Windows Firewall won’t offer you protection against these types of Trojans; it won’t be able to tell when a Trojan is making an outbound connection, so the Trojan will be able to do its damage without your knowledge.
