Most web browsers can be set to disallow popups or disallow sites from opening up other pages.
Some web browsers can use Adblock Plus to stop unwanted ads.
Your post is a little unclear but why go to sites that annoy you?
A web site (ad.yieldmanager) keeps opening ads through it's web page. I have tried to just type in the page, but it doesn't seem to exist. When it opens on my computers I get a series of 3 ads in a row, each opening in a new window. I did a computer search for a file containing the name, but can't find it.
