Faronics Corp. Part of DeepFreeze. It's not malicious, but you'd have to be an idiot to use Deep Freeze.
It's basicly something very useful for computers at schools, preventing children to install games or chat programs.
Needed for DeepFreeze application - Good security program for use on PCs with multiple users. Works well in Schools, Libraries, and other locations where you want users to be able to do whatever they want and then easily restore to your default configuration with a simple reboot. Removes spyware and viruses that a user may have come in contact with.
