Comodo states that in the VD they have implemented anti-screen-capture, anti-keylogging (by using the virtual keyboard), etc. However, I have seen no thorough testing of the Virtual Desktop against such malware to verify that it works as stated. Now, I'm not saying it doesn't work - but at the same time - I am not saying it does protect the system more than the "regular" CIS sandbox. Don't know...
I - as well as others on the forum - spent a lot of time to arrive at a better understanding - unfortunately, to no avail.
On the Comodo forum, there is a long thread (from about the time of late v. 6 or early v. 7) where a lot of dedicated users ask the question: What protections will\does the VD provide - exactly?
To make a long story, very short - in the end, the reply from Comodo was "We assure you that it all works..."
Not very reassuring if you ask me. Lots of users were disappointed on the lack of explanation.... but, as you know, the forum is not really a support forum.
From what I see, the VD is nothing more than a fancy desktop background that functions the same as Comodo's "regular" sandbox. I noticed no difference in CIS behavior or protections against malwares from the MT Malware Hub when tested in both the sandbox and the VD.
That's not to say there aren't additional protections... but I have been unable to obtain any additional infos other than the very limited discussion in the manual or on the forum.
Sorry, wish I could provide you with more infos...
Best Regards.
