Nice concept but not gonna happen anytime soon... it's just too small userbase, too many dependences, too many possible bugs. Just not gonna happen.
Gee, how many times have we heard this in the security world and then got screwed over...
This is
not the attitude to have for a security company.
Sure, it is just a concept right now. But hackers love to make proof-of-concepts, release that to the public, them we get hit with new security threats.
If avast wasn't to get/stay on stop, they need to at least be aware of this and have some sort of plan.
