Prevention vs. Reaction
Anti-virus software is based on a concept of waiting and reacting to new malware and other threats developed and released on the Internet. An untold number of computers and computer systems are severely damaged before most anti-virus providers react and race each other to be the first to develop and deliver new security updates to fight new threats.
This reactive concept of traditional anti-malware security technology comes with a built-in and fatal flaw: The constant need for signature updates.
BufferZone Needs No Signature Updates
BufferZone's preventative and proactive security requires no signature updates or reactionary security decisions - ever. Computer systems protected by BufferZone are constantly and automatically protected from any known or unidentified malware such as viruses, spyware, Trojans, rootkits, keyloggers, phishing and more, even if you happen to be the first to download the newest threat.
The Virtual Zone
BufferZone's unique application virtualization technology transparently redirects any potentially threats such as browser based applications or other downloaded desktop applications to an isolated virtual environment called the Virtual Zone protecting your actual system from dangerous Internet threats.
BufferZone's technology should not be confused with PC virtualization software such as VMware or Virtual PC and does not consume resources, memory and CPU space the way PC virtualization software does. Moreover, it fits into your existing Windows environment with no need to create or manage a separate virtual environment.
BufferZone application virtualization merely redirects PC modifications by Internet and downloaded programs to a separate environment labeled C:\Virtual on the hard drive while Windows and its processes continue to run normally within their usual environment. It's as if those programs and files never modified anything on your actual system and your PC's system configuration and registry (OS) stay clean and out of harms way.
BufferZone classifies Internet programs and their downloads as untrusted by default, automatically blocking all entry or writing attempts (modifications) by any form of malware. By isolating untrusted programs and files inside the Virtual Zone, BufferZone prevents hidden and malicious applications from watching or damaging your PC's assets.
