Windows 10: Pesky dialog box "microsoft has identified a potential security"

Hi,
I'm getting this pesky dialog box when I open certain documents in Word 2016.

I've tried Adding a trusted location in Trust Center, didn't work.
I also tried the options under Macro Settings, didn't work.

Any way to get rid of this?
Any help much appreciated.

:)

 

Microsoft Security and Maintenance Dialog Box

Just a baby, here, trying to figure out how to recognize trouble:

My Security and Maintenance Dialog Box has grayed out (and made inaccesible) Security boxes for Windows Update, Spyware and Unwanted Software Protection, Microsoft Account, Windows Activation; and for Maintenance Messages has grayed out Device Software and
Startup App]s. The grayed out boxes are checked, but should they be inaccessible? [and are only faking being on?]

Just checking. Thanks for your help for the incognoscenti....

Open and Save As Dialog Boxes not working

Hello,

If the Open and Save As dialog boxes are not appearing, there might be a process or service that is conflicting with that function of Windows. We recommend that you perform a clean boot of Windows. This would aid eliminate software conflicts that occur when
using Windows.

Note: Your computer may temporarily lose some functionality when performing a clean boot. If you start the computer normally, the functionality returns. However, you may receive the original issue.

Here's how to perform a clean boot environment in Windows 10:

• Press the Start button, then type msconfig, and select
  System Configuration from the search results.
• On the Services tab of the System Configuration
  dialog box, click to select the Hide all Microsoft services check box, then select
  Disable all.
• On the Startup tab of the System Configuration
  dialog box, click Open Task Manager.
• On the Startup tab in Task Manager, for each startup item, select the item and then click
  Disable.
• Close Task Manager.
• On the Startup tab of the System Configuration
  dialog box, click OK, and then restart your computer.

After performing a clean boot environment of Windows, see if the Open
and Save As dialog boxes work as they should be. If it works, then you may follow the steps below on how to determine what is causing the problem while in a clean boot environment:

• Log on to the computer by using an account that has administrator rights.
• From Start. search for msconfig, then select
  msconfig or System Configuration from the search results.
• Click the Services tab, and then click to select the
  Hide all Microsoft services check box.
• Click to select the upper half of the check boxes in the Service list.
• Click OK, and then click Restart.
• After the computer finishes restarting, determine whether the problem still occurs.
  • If the problem still occurs, repeat steps 1 through
    5, but clear the lower half of the check boxes in the Service
    list that you originally selected.
  • If the problem does not occur, repeat steps 1 through
    5, and select only the upper half of the remaining check boxes that are cleared in the
    Service list. Repeat these steps until you have selected all the check boxes.
  • If you still experience the problem when only one service is selected in the
    Service list, this means that the selected service causes the problem, and you should go to step
    10. If no service causes the problem, go to step 7.
• Repeat steps 1 and 2 in this section.
• Click the Startup tab, then click to select the upper half of the check boxes in the
  Startup Item list.
• Click OK, and then click Restart.
  • If the problem still occurs, repeat steps 7 and 8, but clear the lower half of the checked boxes in the
    Startup Item list that you originally selected.
  • If the problem does not occur, repeat steps 7 and 8, and select only the upper half of the remaining check boxes that are cleared in the
    Startup Item list. Repeat these steps until you have selected all the check boxes.
  • If you still experience the problem after only one Startup Item
    is selected in the Startup Item list, this means that the selected
    Startup Item causes the problem, and you should go to step
    10.
  • If no Startup Item causes the problem, a Microsoft service probably causes the problem. To determine which Microsoft service may be causing the problem, repeat steps
    1 through 6 without selecting the Hide all Microsoft services
    check box in each step.
• After you determine the startup item or the service that causes the problem, contact the program manufacturer to determine whether the problem can be resolved. Or, run the
  System Configuration utility, and then click to clear the check box for the problem item.
