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.
With Shadow Defender, you have the flexibility to specify which files and folders are permanently saved to the real environment. This ensures important files and folders are kept after a reboot.
If you want to make a maintenance-free computer, Shadow Defender will be your best choice.
I rather store my important files on a separate 2tb external hard drive.
and if i ever got a virus id simply reinstall os it's quicker and less of a headache then trying to remove it.
