Troubleshooting Popups and Chrome:

Two Things...

A. Scan for Malware:

Scan with Malwarebytes for Mac:

Malwarebytes searches for malware (short for (malicious software) and spyware. Those make your Mac act in a mislead manor. So scan with it, and remove what is found from the quarantine. It is created by longtime users of these forums making it the only reliable Security Software for a Mac. If synced with iPad connected, it may have got installed on your Mac.

Downloads:

1. Malwarebytes Anti-Malware for Mac
2. Malwarebytes Uninstaller

And...

B. Clear your Temporary Internet Files:

Boot into Safe Mode and then...

a. Clear cache & cookies of Chrome

b. Clear your Temporary Internet Files of Safari:

1. Booting into Safe Mode: [hold down shift upon boot until the login screen appears]. See if this is still an issue. Safe Mode lets items run as default, without changes whatsoever. That is possible because caches of your macOS are temporarily disabled while in Safe Mode
2. Clearing your Temporary Internet Files (Cookies & Cache) of Safari: Cookies perform remembrance of certain site-entered data. Whereas Cache keeps a snapshot of the last time you visited a site.  Use this Link: Clearing History and Cache - Apple Communities

That could mean the site you are visiting is allowing advertisers to do this; or that it is scammers. You can try an ad blocker for the browser you are using. And, you can use a different browser (one whose developer does not depend on advertising revenue as their sole source of income).

Does it also occur if you use Safari?

The solution depends on whether the problem is system-wide or is limited to Google Chrome.
