How does Deep Freeze works?
Technicilly speaking, the Deep Freeze is a kernel-level driver that protects hard drive integrity. When the Deep Freeze is activated, the information being written to the hard drive will no longer be referenced once the computer is restarted, and leaving the original data intact.
Deep Freeze can even protect your computer from harmful malware, and spyware because it will automatically delete the downloaded files when the computer is restarted. However, it does not provide real-time protection, and if you think that your system was infected by malicious spyware, or malware then all you need is to restart your system to remove them.
