Pop up message when converting

[regansa]

I am merging TWO pdf files and ONE RTF file. All of a sudden I started getting the following message just about 3 times every time I merge my files. I spend all day merging so it is getting to be super annoying. I can't seem to find a way to turn it off and have no idea why I am starting to see it. 

"Do you trust the source of this file and want to convert it?"

Any help with getting this message to stop appearing would be fantastic! 

Thanks,

Steve

PS When I tried googling it said to change the setting in the PostScript/EPS and I have but still get the message.

Hello,

I have the same issue as Steve and have tried both solutions of updating settings for PostScript and edited regedit from this article https://helpx.adobe.com/lv/acrobat/kb/security-warning-postscript-pdf.html but I keep getting the same error (see below) has there been a fix made forthis buy any chance or any updates

Thank you

Steven
