Google discovered a major security flaw in Chrome and the put out an update for it on Thursday.
In the upper right hand corner of the browser window — you should see a big GREEN ARROW. Please click it and choose the update option. The update will get applied and Chrome will re-open in about 2 minutes or less.
If you don’t see the arrow — it means you probably already have the update. But to be sure — click on the “3 dot menu” in the upper right (where you go to get Chrome settings). Click Help — click About Google Chrome. Version # should be 72.0.3626.121
