Virtualization: A Defense Shield*

The premium* version of the ZoneAlarm Security toolbar incorporates virtualization technology, which creates a temporary, isolated area in which stealth attacks and junk are trapped and deleted without harming or cluttering your PC.

For example, drive-by download spyware can be automatically and silently downloaded to your computer. Even well-known Web sites have been compromised by drive-by download criminals. ZoneAlarm browser security catches and deletes these drive-bys within a virtual operating system so they never make it to your real hard drive.

When you choose to download something, it is allowed to pass the virtualization shield and be saved to your PC. For this reason, other ZoneAlarm browser security features are designed to detect deceptive sites and block dangerous downloads.
