A family of Microsoft word processing software products for creating web, email, and print documents.
I solved this by uninstalling the Bluetooth program, which I had no use for.
The answers given here are awful. The fire alarm analogy is stupid. If your fire alarm is put out of work, what's the worst that could happen? A fire goes off, there is no alarm, and your house and perhaps the whole city burns down.
If your Microsoft Word template changes without your knowing it, what's the worst that could happen? Uh, not much, besides the Microsoft Word template changing without your knowing it.
It is my analogy and I think it is apt, if perhaps a little dramatic. The thing is that the template being referred to is the "normal" template in Word. It houses much of what makes the program work the way it does. The message that something is trying to change that is an important one to Word users.
Changes to that template can make Word stop working, or work in very unpredictable and unpleasant ways.
In my business, if Word stops working I may be out of business. I will at least be shut down until I can figure out an alternative. Changes to the normal template by malicious software are real. So are stupid changes made by well-meaning software. I want changes to my normal template to be ones that I know about and approve.
With a smoke detector that keeps going off, I look for the source of the smoke. I do not simply turn the smoke detector off and assume that everything is fine now that the alarm is no longer going off.
With the Word alert, I look for the source of the change if that source is not a deliberate change that I made. You did that - you unistalled the Add-In. You did not, I hope, turn off the alarm.
