What is this Pop Up? Is it harmful and how do I get rid of it

Recently, my desktop computer is now showing a Flash player pop up (see above) that comes on about every half hour and remains for about 10 seconds
The appearance of it about 2- weeks ago seems to coincide with Adobe ending Flash player last month and notifying people to uninstall it in their computer
I checked and I don't have flashplayer on my computer - hence cannot uninstall it
The only thing that it appeared to affect was my Microsoft 360. I had a powerpoint that had an embedded video that when I activated
tried to use flashplayer and it corrupted the program, to where Microsoft 360 would not operate and I had to uninstall it.
I also reset my Google to original settings and that does not prevent it.
I ran scans on my computer and start up apps and neither identifies it at all, let alone as malware.
Have you seen or heard of this popup and any advice on how I can get rid of it?
Thanks for any info or assistance you can provide
