When I print to PDF using the Adobe PDF printer (same as I have done for 10+ years), I am now getting a security alert box that pops up and asks me "Are you sure that this file is from a trustworthy source and you want to convert it? Yes or No". I have not changed anything with my AutoCAD Map 3D settings or my Adobe settings. It just started yesterday and it does it to every drawing I have. I haven't seen this before so does anyone know what this is? It doesn't happen with any other program when I print using the same Adobe PDF printer.
