Use a pop-up blocker

Pop-ups aren’t just annoying; they can potentially contain malware that will download if you click on them. Virtually all major browsers either have pop-up blocking built-in or have easily downloadable extensions that block pop-ups. Whatever browser you’re using, make sure you’re using a pop-up blocker. However, it’s not necessary to use it for sites you’re comfortable with, and some pages won’t even function properly if you have a pop-up blocker enabled, so it’s okay to whitelist these sites.
