strange Edge messages lately

Hello; recently my Edge browser, (WIN 10, Dell desktop) has two strange messages: 1) When I go to close Edge, a message says "Are you sure you want to close? You're still downloading files", and I'm not downloading anything..... Second message at bottom, "What do you want to do with usync.nexage.com: open, save, or delete", I delete of course, not knowing what the heck this is. Typical sites I visit are CNN, Weather, Market Watch, Lowes, etc. This just started this week, so what's happening, why suddenly, and how do I stop this madness? Thank you, Steve in Sac.

 

Hi Dave; my WIN 10 version is 1709, Home Edition, so it's downloading to be 1803? I just turned off the "Sync Favorites, Reading List, etc across all devices" in Edge settings, I'll see if that helps. And, what do you make of the other message re: "What do you want to do with usync.nexage.com: open, save, or delete", are you familiar with that message? Thanks.

 

Scanned with Norton, GREEN check, no virus, but that message still pops up. Also, unchecking the 'sync all devices" did not work, still getting same message "you're not done downloading..." when closing Edge. I'm ready for more suggestions! Thanks, Steve

 

I think this may be solved; since it only started 1-2 weeks ago, I see online now that more people are getting the same thing, "mapuser-providerid, usync.nexage". It is apparently due to a bug in the Microsoft ad network code, probably from an update they sent out. I read that I should upgrade to the latest Edge version, but I think Microsoft may have fixed it today, probably with an Update, it's not happening today! I'll watch & see if it's gone permanently, and post here. Thanks. Steve
