3 Remove Potentially Unwanted Programs

Potentially unwanted programs, or "PUPs", often arrive bundled with your computer or can tag along with another software program you meant to install. Most times, they are snuck into the EULA as a "Recommended Offer" that many of us are so accustomed to just click right through. Lots of these types of programs end up being junkware that your computer will not benefit from. Unfortunately, some of these programs can add unwanted browser toolbars or extensions that can clutter your browser, track your web browsing, show additional advertisements, or change your search page and other related settings. Usually, unless these types of programs are removed, they will continue causing issues with your web browsing experience.
