I started using this a few days ago and I'm VERY impressed. This app is my introduction to sandbox programs and I really like what I see. Provided your PC is clean when you install it, it's difficult for me to see how a rogue app trying something akin to backstealth, firehole, tooleaky, etc..., could be successful. The learning curve on this thing is pretty steep, and there definitely exists the potential to misconfigure it in such a way that you could seriously destabilize your system, but this is one sweet app. I'd be very interested to hear if anyone else has tried it out and what their thoughts are. So far I see no compatibility conflicts with my other security software.
