THE ULTIMATE VIRUS PROTECTION : SANDBOXIE

type='html'>

Sandboxie runs your programs in an isolated space which prevents them from making permanent changes to other programs and data in your computer.

The red arrows indicate changes flowing from a running program into your computer. The box labeled Hard disk (no sandbox) shows changes by a program running normally. The box labeled Hard disk (with sandbox) shows changes by a program running under Sandboxie. The animation illustrates that Sandboxie is able to intercept the changes and isolate them within a sandbox, depicted as a yellow rectangle. It also illustrates that grouping the changes together makes it easy to delete all of them at once.
