Doing nothing special on my Win10 pc, in Chrome, an apparently Abobe window opened and told me to update Flashplayer. This occurs at approx 10:45pm EDT. Because I always have my browsers display the URL showing where I am, I glance up and see not adobe.com but ...
I closed the window immediately, then searched for the domain and found ... no hits.
I can only presume an infection on my pc, so will run Malwarebytes, Windows Defender, and whatever else I can.
HOWEVER, in case it is *not* a local problem, it only makes sense to alert Adobe and its users by posting the suspicious link.

Yes, this is absolutely fraudulent update notification. Someone reported the same issue on the same domain yesterday and I forwarded that to our fraud department. Your URL is slightly different and I have forwarded your URL to the fraud department as well.
I recommend running full scans on your system for malware, virus, etc.
