If your computer doesn’t have any anti virus program installed during the unlocking of deepfreeze, the probability of your computer to be infected with virus or worm is high, especially when working in network environment.
Deepfreeze is an application which allows users to protect the core operating system and configuration files on a computer by restoring back to its original state each time the computer restart.
Sounds good but the downside, you can’t update operating system patches and same to online games. If you want to make changes, you have to unlock first the deepfreeze program to allow any changes to take effect and activate it when done.
My advice is, install the deepfreeze program and antivirus.
