Sorry to hear about your experience with the application installation.
McAfee is an optional installer with Acrobat Reader. You may disable the installer option from the Acrobat Reader installer page.
You may install it directly from the following page without add-ons: https://get.adobe.com/reader/enterprise/.
Hope the information helps.
