Are you talking about advertisements or pop-ups?
Those are two entirely different animals.
Pop-ups are required for the site to function properly.
The Browse window for images on the listing form is a pop-up.
The Enlarge feature on eBay listings is a pop-up.
You need to uncheck your pop-up blocker on your web browser.
Advertisements are a different story. You need not put up with those.
Run a good malware tool such as Malwarebytes on your system:
And, if you continue having problems, use a web browser that doesn't allow advertising, such as Firefox.
