ZoneAlarm claims that the tactic stops phishing, drive-by downloads and key-loggers sending data out onto the web.
The firm highlighted a proliferation of malicious websites, or sites that have been compromised by hackers, that take advantage of browser vulnerabilities to silently install malware.
To neutralise such treats ForceField's virtualisation forms a "bubble of security" around the web browser so that all unknown or unwanted changes from these silent installs, or downloads, are made to a virtualised file system that disappears completely once the user is finished surfing.
This also protects against any malware that might already be on the PC.
ForceField is less than 4MB in size and installs immediately without requiring a system reboot.
