Pop-up ads are almost impossible to avoid, but you can reduce them significantly. However, if you have an extreme number of pop-ups the chances are you probably have adware infecting your browser.
Ensure that you have your browser’s pop-up blocker turned on, have good security software, and always watch when installing or downloading new apps or programs for additional bundled software or toolbars that propagate pop-up ads.
Turn on Pop-Up Blocking in Browser
All major browsers have settings to control pop-ups. In Firefox, the check box to block pop-ups is in the Content tab, also under the browser’s Options. Chrome users have to dig further. To find the Pop-ups settings, scroll down the Content Settings menu, which can be accessed in the Privacy section of Advanced Settings.

Pop-ups can be the result of adware. You can download adware unwittingly by not reading license agreements or paying attention to check boxes while installing new apps and software. Clicking on an ad or pop-up, even to close it, can cause you to pick up adware just like a real-world virus. To safely close a pop-up, open “Task Manager” by pressing “Ctrl-Shift-Esc.” Pop-ups display in the Applications tab. Click on it and then press “End Task.” Another way to stay safe is to avoid adding toolbars you haven’t researched. Some examples of common adware toolbars are Ask, Babylon and Yahoo
