Hi all,

I have Office 2016 for Mac, and when I add a link on Powerpoint, on opening it appears the message:

"Opening path/filename.
Some files can contain viruses or otherwise be harmful to your computer.
It is important to be certain that this file is from a trustworthy source.
Would you like to open this file?"

Then you can give the approval to continue and it opens.

This is happening when I add a hyperlink of a PDF file or video file that is saved on my Mac (El Capitan).

On the other hand it works properly if I add a hyperlink of :
1. The web
2. Word file
3, Picture

I disabled Macros and turned down firewall but same issue.

Any ideas?
