The web's 10 best free security downloads

Keep your PC safe with these 10 free tools

We've rounded-up our 10 favourite security downloads for Windows that will help to keep your personal information private and secure.

Comodo Firewall Pro

The firewall that ships with Windows XP or Vista simply isn't good enough to keep you safe — you need better protection. There are plenty of free firewalls out there, but our favourite is Comodo Firewall Pro, which provides top-notch protection from both inbound and outbound threats. It offers other types of protection as well, including what it calls Defense+, which keeps you safe in several ways, including locking down certain files and folders so that they can't be altered.

Note that this firewall is more aggressive than many in asking whether you should allow connections. So when you first run it, expect to see a good many pop-ups asking whether you want to let through a particular application.

To help cut down on the pop-ups, run its Clean PC mode, which lets you scan your PC for applications and then register them as safe so that you're not inundated with quite so many pop-ups. In addition, there's an 'install mode' that disables certain types of pop-ups for 15 minutes, allowing you to easily install new software.

Another very good free firewall is Online Armour. The free version is excellent but with one shortcoming: to install a new version, you first have to uninstall the old version, then install the new one.
