BufferZone Pro

BufferZone Pro is a unique system security suite that uses virtualization technology to protect your computer from any type of external threat by isolating new files and programs from the rest of your operating system. The program creates an isolated environment called the "Virtual Zone" in which all new applications and files are run until you decide that they are safe to be moved into your "real" computer environment.
The entire process is seamless and fully automated. You will see a thin red border around any window that is currently run from the Virtual Zone, indicating that the program cannot make any modifications to your hard drive and registry.
BufferZone is ready to use immediately and automatically protects popular browsers, instant messengers and download clients. If your favorite programs are not protected by default, you can easily add them to the list. You can also run any previously downloaded file or program inside the Virtual Zone by choosing the option from the Explorer right-click menu. Other features includes advanced application rules, and integrated firewall (for apps inside the buffer zone), external drive virtualization, personal file protection and more.
