Chrome browser frozen from scam tab. How to fix? I got an ad popup in a new tab in the Chrome broswer from visiting a site &amp; now that tab ad won't close or let me use Chrome. 

Tried force stopping &amp; clearing cache but Chrome is still frozen. Tried restarting phone. No change. See the photo for the tab that won't close.  It's the "critical..." one that has frozen Chrome. Can't close any tabs at all too. Any suggestions? Also,  Malwarebytes' scan result = nothing.
You could always uninstall chrome, and then reinstall. That's assuming you don't have any bookmarks you care about.
