ZoneAlarm offers plenty of paid security products including the typical security suite and antivirus offerings, alongside more unique protection against online shopping fraud and identity theft. As well as their big name products and trial editions, it also offers some completely free software. ZoneAlarm Firewall is one such piece of software – a watered down version of the companies’ full internet suite.

Online Armor is a free firewall program that offers increased functionality far in advance of that seen in Windows’ own firewall program. Kernel mode security, script protection and a process guard are amongst its range of features, so if you’ve been using Windows firewall to protect yourself from online attacks in the past, you’re in for a pleasant surprise.

Fancy getting your hands on some registered antivirus software for free? We’ve got 20 Edit 50  free keys for the professional version of Comodo Internet Security.

Comodo Internet Security is a security suite designed to protect your computer from malware. It includes a fully functioning firewall, a malware scanner — capable of removing viruses, trojans and adware — real time port monitoring, automatic updates and the ability to manage system processes.
