Free Firewall

A computer with an always-on connection makes it especially vulnerable to information theft and other attacks.
(Not necessarily needed if you have a hardware firewall built into your router.)

ZoneAlarm - Download Here

ZoneAlarm is designed to protect your DSL- or cable-connected PC from hackers. This program includes four interlocking security services: a firewall, an application control, an Internet lock, and Zones. The firewall controls the door to your computer and allows only traffic you understand and initiate. The Internet lock blocks Internet traffic while your computer is unattended or while you're not using the Internet, and it can be activated automatically with your computer's screensaver or after a set period of inactivity. Zones monitor all activity on your computer and alert you when a new application attempts to access the Internet. 

The FREE Basic version of ZoneAlarm is for individual and not-for-profit charitable use .

If yours don't look similar or better than this, you should install a firewall.

Note: Installing a router, with a built-in firewall on your broadband connection, is the best first line of defense.
