i had the same issue so would suggest you to remove ad extension and untrusted bars and make sure you reset your browser. and remove the unwanted programs from computer .
and i am sure this will help ..thanks
there are popup blockers built into different browsers, and as long as you turn them on that should be sufficient. What browser do you use?
Also if you get a lot of popups it could be that you have adware on your machine, try downloading and running malwarebytes free scan to clean this. https://www.malwarebytes.org/
