Under the right circumstances this could happen to any soft including your beloved AV and just think of the access it has to the system.
Though no need(yet) to run out the door and into the street with arms outstretched screaming
"They`re here already" "They`re among us now" when the next update sorts it out.
A good ole kick in the pants is needed everynow and again to shake up things up a bit, I just hope the person who stumbled on it gets the full recognition for it.
