1. Deep Freeze, by Faronics, is an application available for the Microsoft Windows, Mac OS X, and SUSE Linux operating systems which allows system administrators to protect the core operating system and configuration files on a workstation or server by restoring a computer back to its original configuration each time the computer restarts.The other interesting salient features are mentioned below :
- Deep Freeze is a kernel-level driver that protects hard drive integrity by redirecting information being written to the hard drive or partition.
- Leaves the original data intact.
- The directed information is no longer referenced once the computer is restarted, thus restoring the system to its original state at the disk sector level.
- Allows users to make 'virtual' changes to the system, giving them the appearance that they can modify core files or even delete them, and even make the system unusable to themselves, but upon reboot the originally configured 'frozen' state of the operating system is restored.
- To make changes, a system administrator must 'thaw' the protected partition by disabling Deep Freeze, make any needed changes, and then 'freeze' it again by re-enabling Deep Freeze. These changes become part of the protected partition and will be maintained after restarts.
2. Deep Freeze can also protect a computer from harmful malware, since it automatically deletes (or rather, no longer "sees") downloaded files when the computer is restarted. The advantage of using an application such as Deep Freeze antivirus / antimalware is that it uses almost no system resources, and does not slow your computer significantly. The disadvantage is that it does not provide real-time protection, therefore an infected computer would have to be restarted in order to remove malware.
