The document seemed to only say: Adobe Reader 8 For Macbook Pro I recently received an attachment and when I previewed it in Google Apps, I saw what you see at the top of this post. The actual developer of this Mac application is Adobe Systems. Our built-in antivirus checked this Mac download and rated it as virus free. The program lies within Productivity Tools, more precisely Office Tools.
Hopefully this helps you if you are having this same issue. If you don’t have Adobe Acrobat Pro you could just download the latest version of Adobe Acrobat and that would have worked as well.
