(I posted this to alt.comp.freeware on July 6, 2014. I found since posting this that the despite my refusing the download after reading the notice, the site had already installed rkinstaller.exe onto my machine. Kaspersky AV caught it and got rid of it.)
I began to downloaded a freebie called MOV Player from -
http://www.easyfreeware.com/files/mov_player.zip/1
74509
When installing, I see this notice:
" Welcome to the MOV Player Setup Wizard
This will install MOV Player 1.0.2 on your
computer.
By clicking "next" you agree to initiate the
installation process, which will include a small
piece of software used to verify your acceptance
of our partner's disclosures. This verification
software is removed when you reboot your
computer."
Does this "small piece of software" which verifies
acceptance of their "partner's disclosures" mean
what I think it means? Is it another deceitful way
of getting my "permission" to load other junk on
my machine, or loading spy garbage which uploads
info back to some outfit or other? Am I getting
too paranoid, or what?

It seems I was right to be paranoid.
