Spam Android notifications - Chrome

I am getting many spam notifications per day, asking me to click here for further information.  They shows as coming from "movfinb.com" and are via Chrome notifications.  However, I do not get them on my PC or laptop.  There are many messages a day saying "your phone has been infected - click here!".  Lately I am also getting many news notifications on Chrome (to my phone, but not PC), also showing the movfinb.com site, which are referencing a news story from Yahoo.com.   I am not clicking on any of these, but am wondering what I can do to deal with these.
