Sandboxie Plus runs programs inside an isolated container that intercepts file, registry and network writes, so anything malicious is discarded when the sandbox is emptied and never reaches the real system.
The Plus branch adds a Qt-based interface, snapshot management, per-box network restrictions, forced programs and encrypted sandbox storage on top of the classic core. Licence activation is already applied, unlocking paid supporter features such as box encryption and the run menu.
