Issues with popups and Sign-in needed to use Word

[JP27VA]

(NOTE: I'm not a tech "natural") I've had this unit for about a month.  I suddenly have 2 issues: 1. Last week, these pop-ups started popping at the lower right of the screen, and I have to hit "Close" to get rid of them.  Some claim that I have a virus, but I don't.  They've settled into a pattern of about three at a time, every half-hour or so.  Royal Family gossip, health items, news.. some seem related to my web activity.  Anybody know what this is?  2. Starting yesterday, I have to Sign-in (white button upper right) to use Word properly (Zoom, for example).  I did go into the "checkbox jungle" to see if a setting was causing problem #1, but I don't think I changed anything.  Maybe I did... any help ius appreciated - this is causing me time loss.  NOTE:  Windows 10, Office 365, non-Cloud.  Thanks,  JO

Sounds like you saved file(s) on OneDrive (by mistake because you are a non-cloude user). You can turn off OneDrive, please try
