Tracking Cookies Hard to Stomach? How to Stop Them


You know the drill: You visit a website — to price sneakers, view kitchen countertops, whatever — and when you continue to surf the Internet, you’re stalked by advertisements for Nikes and granite.

So-called first-party cookies come from the sites you access, and they can be useful: You avoid having to reenter the same information on subsequent visits. But third-party cookies that haunt you from site to site can be harder to stomach.

Software such as CCleaner can identify and remove existing third-party cookies on your hard drive. To prevent future third-party (or all/select) cookies, you need to change your browser settings.
