Shadow Defender 1.2 was available as a giveaway on May 1, 2013!
Shadow Defender is an easy-to-use security solution (for Windows operating systems) that protects your PC/laptop real environment against malicious activities and unwanted changes. Shadow Defender can run your system in a virtual environment called 'Shadow Mode'. 'Shadow Mode' redirects each system change to a virtual environment with no change to your real environment.
If you experience malicious activities and/or unwanted changes, perform a reboot to restore your system back to its original state, as if nothing happened.
Windows XP, 2003, Vista, 7, 8
