Security prompts appear during my presentation

Symptoms

Security alerts from the Microsoft Office Trust Center appear when you open your presentation or click certain content in your presentation.

Cause

Your presentation contains content that might not be secure (for example, an executable file or a macro). By design, the Trust Center checks all files that might not be secure and displays a security alert.

Resolution

You can use Presenter view to prevent security alerts from appearing where your audience can see them. Security alerts appear on the presenter's computer screen, but not on the projector (or screen) that the audience sees. To enable Presenter view in PowerPoint, see View your speaker notes privately, while delivering a presentation on multiple monitors.

If you don't want a file to be checked by the Trust Center while you deliver your presentation, before your audience arrives, move your presentation to a trusted location on the computer on which you plan to deliver your presentation. For more information, see Add, remove, or modify a trusted location for your files.

To maintain a protective level of security, we recommend you do not change settings in the Trust Center. For more information about Trust Center security and privacy settings, see View my options and settings in the Trust Center.
