If you are on your desktop you may see a little red arrow on the top right of your screen. That is Chrome telling you that it needs to restart to install an update, and it may be in your interest not to ignore it any further.
Google has just released an update for Chrome that addresses 3 serious security bugs, one of which is being actively exploited in the wild.

Google confirmed that it is currently being exploited, but did not say where. Instead an update to Chrome version 80.0.3987.122 is now available for Windows, Mac and Linux, and you can update by tapping the aforementioned arrow, or by going to Help > About Google Chrome.
