After my computer re-booted, I was told that an update for adobe was available. I clicked the button, and another textbox displayed that not only was I downloading the adobe update, but my computer was being infected with McAfee software (a 2nd installation), therefore, I aborted the "update" installations.
Not only do I consider this consumer issue unethical, it should be illegal for a software company to foist another companies product on consumers without their permission.
