ZoneAlarm

A firewall should be one of the very first programs you put on your machine. If you don't already know, a firewall is absolutely essential in preventing hackers and other cyberthreats from accessing your PC. Unfortunately, many of them can be tough to configure, baffling even seasoned geeks. Not so for ZoneAlarm, one of the most trusted firewall utilities on the scene. The program walks you through the set-up process, offers several levels of security, and doesn't overload you with a bunch of highly technical jargon. Just set it and forget it, and you'll sleep well at night.
