Clearly nasty of M$ to do a stealth install, especially to a product that is not their own.  And that is one of the things I dislike about them so much.

What I did not see in those posts was whether there was any actual harm done by it.  There was a reference to "killing my firefox" but no specifics and I think the reference was in the cartoon.
