GesWall Intrusion Prevention System; free and easy security?

Security software company GentleSecurity offers a free version of their Intrusion Prevention System called GesWall.

Described as a sort of cross-over between a HIPS and a sandbox, this program allows you to completely restrict your internet facing apps in modifying your system, files and registry.
For example, when you use Internet Explorer or Firefox and you're suddenly hit by a drive-by download and/or a trojan tries to modify your host file; redirecting your browser or tries to steal private information or install other malware, GesWall will not allow any of it. Full stop.

GesWall allows you to restrict unwanted modifications with ease by 'isolating' applications.
It does not require you to click on endless popups; it isn't much 'in your face' and the standard configuration simply works (well, for most people).
It allows for detailed customization but you don't have to, to make it work.

Matt from Remove-Malware.com has posted a Youtube video in which he explains how simple it works, how easy it is to install software you do want while running GesWall and how easily it stops malware from causing harm. (almost everything explained in the video is available in the free version).

If you already run a firewall with HIPS like Comodo's or Online Armor, a sandbox or a behavioural blocker like ThreatFire, this program might be overkill but for those who like more (free) active protection besides their AV, this program is highly recommended. Watch the video! You'll probably be impressed.
More recent information about the program can be found on the GesWall blog.
Cheers.
