> For many non tech folks where I had replaced IE with Firefox, I now see them using Chrome, and when I asked if they installed it, they usually have no idea how it got on their computer.

Chrome probably got there the same way Firefox got there - a well meaning individual (you, in the case of Firefox) installed it and told them to use it because it is "better".
