What does Time Freeze do? Have you ever heard of sand box by avast? They are somehow close enough but Time Freeze is much bigger. Time Freeze creates a virtual system where it stores anything while you are browsing, downloading and much more. The time you turn it "On", everything before it will be protected and from that moment it will isolate everything that comes in to your PC which protects all of your files. Making key loggers, spyware and trojans useless when entering your PC when Time Freeze is activated. Turning off Time Freeze, you will have two options if you wan't the saved virtual system to be transferred to the real system or discard it.
