Everytime I use Google chrome on my Moto z play I'm getting an Amazon pop up over the site I'm on saying congratulations you've won. I can't get it to stop and can't get back to the page I was on?!?!! As suggested everywhere on line it says this is a virus/malware and suggests to go into apps and find a downloaded app for it. I've looked through all the apps in my settings and cannot find anything. Anyone know what's going on and how to fix this?
