Stop installing unwanted McAfee!

I went to the Adobe Acrobat wesite, downloaded the installer...and it installed Mcafee Antivirus software WITHOUT permission.  This is SOOO shady!   I've seen previous complaints that the same thing happened to other people, but at LEAST they seemed to have a dialog box or checkbox to opt out of the breach of privacy.  AT NO POINT DID IT GIVE ME ANY OPTION TO NOT INSTALL, nor did it EVEN TELL ME IT WOULD install until it actually installed!  At least give me a CLEAR WARNING AND OPTION TO NOT INSTALL!!!!  WTF?!?  This is acceptable now Adobe?  This feels like such a breach of trust.  Just, no.  Stop.   Sneaky as F.
