First Look video: ZoneAlarm

An important part of every computer user's security is the software firewall. If you don't have a secure hardware router, a program like ZoneAlarm is the perfect choice to keep hackers out and to prevent rogue programs from contacting the bad guys.

Every computer user needs security software to keep him or her safe on the Web. Along with antispyware and antivirus programs, a good software firewall is a must-have to keep hackers away from your data. Firewalls also are useful for determining which programs are making contact with outside sources. If you're looking for a solid software firewall, look no further than ZoneAlarm .
