How to Stop Scam Pop-Ups in Google Chrome

What are "scam" pop-ups?
Browser-based tech support scam "warnings" are becoming increasingly more common. They are designed to look official, pretending to be from Microsoft, Google, your internet provider, or another legitimate company.
These messages will claim that your computer is infected, that your data is at risk, or that your computer has been "blocked" because it has been hacked. At the end of their scary warning, they will provide a telephone number and urge you to contact them for support.
There is most likely nothing wrong with your computer.
These are false messages designed specifically to frighten you into contacting the provided fraudulent "support" line, where an individual will attempt to sell you unnecessary support services or software, and will ask to remotely control your computer. By no means should you ever call one of these numbers or let them remotely control your computer.
In the vast majority of cases, there is absolutely nothing wrong with your computer. Unfortunately, the way these browser-based tech support scams are displayed, they can be very difficult and sometimes impossible to close via traditional means.
The following steps will walk you through terminating your browser to clear such messages, and help resolve other problems with pop-ups you may encounter.
