Wood, meet the trees.
A representative of anti-virus vendor AVG recently opined to Vulture South that this incident is likely a precursor to a wave of attacks directed at hypervisors. The spokesperson had no evidence for that assumption, but ....
Well, it would be idiotic to present evidence against yourself, AVG, wouldn't it .... and self-defeating too.
And quite plausibly deniable too, would all evidence in that opinion be, but .... well, you can fool some of the people all of the time, and all of the people some of the time, but you can not fool all of the people all of the time, AVG, or if you prefer, you can fool all the people some of the time, and some of the people all the time, but you cannot fool all the people all the time.
