Sandboxie runs your programs in an isolated space which prevents them from making permanent changes to other programs and data in your computer.
Benefits of the Isolated Sandbox:
Secure Web Browsing: Running your Web browser under the protection of Sandboxie means that all malicious software downloaded by the browser is trapped in the sandbox and can be discarded trivially.
