Zone Alarm - Free Firewall

A good antivirus software is only half a defense. To ensure complete security of your PC, firewalls are also a must. Now, while the free version of Zone Alarm will be of little use against skilled hackers, it will definitely block simple attacks and prevent spyware from stealing your personal data and sending it out over the Internet. A very handy tool to have at your disposal.
