The d!nk plugin is digitally signed with a certificate granted by Comodo (an industry accepted security leader) and verified annually before extending the validity. Macros digitally signed by a trusted publisher can run if you have trusted the publisher at time of installation. All unsigned macros will still be disabled.
In Powerpoint, go to “file” and choose the “Options” menu item
