Our friends at The PC Support Group are back once again with the fourth of their 7 point guide to free software. This week, they look at firewall software to help guard your home office computer against attacks.

A firewall is either a physical device or a software program that sits between a computer or a computer network and the internet to control precisely what can enter and leave.

Zone Alarm by Check Point Software Technologies is one of the best pieces of free (for home users and charities) firewall software on the market. The great thing about it is that it virtually configures itself by learning the behaviour of all the other software on your computer and then reacts if any of them start behaving “out of character”, sending or receiving information when they shouldn’t be.

You can download Zone Alarm from the link below:
