Hi. I can confirm that Deep Freeze 7 is bypassed by the malware known as SafeSys. Some technical information about the malware can be found here: http://www.prevx.com/blog/134/A-puzzle-called-SafeSys.html I knew MebRoot malware was able to infect machines "protected" by Deep Freeze. I even got confirmation by e-mail directly from Faronics, despite I had first hand experience on that. So the conclusion is that if a machine is running with admin rights, Deep Freeze 7 offers no protection at all.
