Answer for The Iphone hack virus and how to get rid of it, if their a way to do that on chrome

I’ve searched this every way I can think of and I can’t find a way to turn off Javascript in Chrome. So there may be another way to close off the windows, but I need a way to test it and I haven’t stumbled upon any scam sites lately. Perhaps close all the Chrome windows and then “shut down” the app by double-tapping the home button and then swiping up?
