I came across this cool feature while playing around with Kaspersky '15. Basically, when you launch a Smart Money Protected Browser (this browser is just a modified, clean install of Chrome), if your computer hardware supports VTx, you are unable to take screenshots while the protected browser is running.I tried doing some research myself (furious Googling, browsing RE websites like kernelmode.info, etc...) but I couldn't figure out how they did it. For more details, check out their troubleshooting section about the technology: http://support.kaspersky.com/us/9955Does anyone have any idea on how this is done? When I try to grab the screen, I just get an entirely black screenshot. I don't know how one can leverage VTx to accomplish such a task. Are they just using VTx to hook all the screen capture syscalls?! Or is there a more interesting way?I'll probably try to poke around with the KAV drivers, but they definitely don't make it easy to RE them. 
How does one leverage VTx to disable screen capture?
