A free version of a popular firewall application

A review of ZoneAlarm Free Firewall by Fernando Ortega

A computer connected to the Internet is subject to intrusion by malicious users. The best remedy against this danger is a firewall such as ZoneAlarm.

ZoneAlarm is a free firewall with more than a decade of experience. Once installed, your computer is behind an impermeable wall in which only you can authorize the passage of data between programs and the network.

The golden age of free firewalls ended when Microsoft decided to include a firewall in Windows XP. ZoneAlarm has suffered, thus a significant reduction in number of users and popularity.

It looks cooler than the original and it certainly does seem to have less configuration options and features. Still, ZoneAlarm is still an excellent firewall.

Features and highlights

  • Detects and blocks viruses, spyware, Trojan horses, worms, bots, and rootkits
  • Makes your PC invisible to hackers and stops spyware from sending your data out to the Internet
  • Monitors programs for suspicious behavior
  • Provides site check, do not track, Facebook privacy scan, private browsing
  • Analyzes downloads and warns you if a download is malicious
  • Monitors your credit and alerts you of changes in your credit files
