Adobe Flash Tries to Pull Some Crap

Y'know what really burns my bacon? When a software update tries to scam you into INSTALLING some other piece of crap.

Looking at you, Adobe Flash Player, and your DEFAULT setting of installing McAfee Security Scan Plus.

And the thing is, Flash has few friends these days and is a dying, decaying platform. So why is Adobe irritating and alienating the few users Flash has left by trying to pull crap like this?
