How To Remove Potentially Unwanted Programs (Virus Removal Guide)

A Potentially Unwanted Program, also called in short as PUP, is a software that contains adware, installs toolbars or has other unclear objectives.

The term “Potentially Unwanted Program” was given by McAfee to avoid labelling downloadable programs as malware. What makes a PUPs different from malware is that the user gives consent to download it. When the user downloads a program from the Internet and neglects to read the download agreement, he or she may fail to understand what other unwanted programs are being downloaded.

Potentially Unwanted Programs usually gets on your computer with freeware software (video recording/streaming, download-managers or PDF creators) that had bundled into their installation these type of programs. These unwanted programs are also bundled within the custom installers on many download sites, so if you have downloaded a software from these websites, chances are that a Potentially Unwanted Program was installed during the software setup process.

In most cases these Potentially Unwanted Programs are adware or browser hijackers. These unwanted programs either hijack your browser homepage and search engine, or displays unwanted advertisements not originating from the sites you are browsing.

Here are a few typical signs that you have Potentially Unwanted Programs on your computer:

• Advertisements appear in places they shouldn’t be.
• Your web browser’s homepage has mysteriously changed without your permission.
• Web pages that you typically visit are not displaying properly.
• Website links redirect to sites different from what you expected.
• Browser popups appear which recommend fake updates or other software.
• Other unwanted programs might get installed without your knowledge.

The first time you install Malwarebytes, you’re given a free 14-day trial of the premium edition, which includes preventative tools like real-time scanning and specific protection from ransomware. After two weeks, it automatically reverts to the basic free version that will detect and clean up malware infections only when you run a scan. It is important to note that Malwarebytes will run alongside antivirus software without conflicts.
