How to Remove Potentially Unwanted Programs (PUPs)

What is a PUP?

A PUP is an acronym (and abbreviation) used by computer security programs to identify a Potentially Unwanted Program, otherwise known as a “possibly unwanted program, grayware, riskware, offerware, or bloatware. A PUP is not necessarily malware or a computer virus and is commonly categorized in the adware, browser hijacker, dialer, remote tool, scareware, and/or spyware categories of computer infections. Other abbreviated terms that are similar to PUP are PUM (Potentially Unwanted Modification) and PUA (Potentially Unwanted Applications).

what is a PUP

Most Antivirus and Antimalware software will detect Potentially Unwanted Programs once a scan is complete. Some PUPs are appended a detection name such as Optional.PUP, PUP.Spyware, Adware.PUP, and more. For example, Malwarebytes Anti-Malware Premium will detect GoPhoto.it as PUP.Optional.GoPhoto.A and will give the user an option to remove the PUP or ignore the program to keep it on the system.

People often mistake a PUP for a computer virus even it is not technically defined as a computer virus. Sometimes when people are infected with a PUP they will referrer to the program as “program name virus.” Although, a PUP is not a computer virus by definition it can still be a dangerous program and put user security at risk the same way a computer virus does. A PUP can also be the sign of a more severe computer infection because the programs will usually bundle with malware, adware, spyware, and other malicious programs.

Symptoms

PUPs have many symptoms since the detection can refer to a number of different programs.

  • Pop-up ads, pop-under ads, in-text ads, and banner advertisements
  • Sponsored search results and new advertisements that appear when you search the web
  • Modified homepage, new tab page, and search engine
  • Slow and sluggish computer
  • Internet browser crash

A concern with PUPs is that they usually bundle with and are advertised alongside other unwanted programs, Malware, and other threats that can remain hidden on a computer system. If a victim did not install a PUP but find it installed on their computer it is likely that the unwanted program was part of a package that bundled it with other objects.

Distribution Methods

Potentially Unwanted Programs are usually distributed via free downloadable content including freeware, shareware, and dubious torrent files. Potentially Unwanted Programs may also be advertised as something they are not in order to trick victims into installing them. For example, a Potentially Unwanted Program may claim to be a browser update, system update, driver update, flash player, media player, ad blocker, browser extension, image, or something similar.

Potentially Unwanted Programs are typically advertised across various websites that contain prohibited content such as video streaming websites, torrenting websites, and pornography websites. These websites utilize aggressive advertising networks that will also advertise malware because the websites are not alloted to display legitimate advertisements by services like Google AdSense due to their prohinited content.

Potentially Unwanted Programs are also bolstered by third-party download managers associated with freeware programs (free programs). Freeware download managers offer PUPs as a custom install and give the user a chance to accept or decline the program from installing. If the user does not opt out from the program installation the program will begin to install alongside the freeware. The way that the custom installation is presented may also be confusig and designed to trick the user into installing programs they did not mean to install. It’s advised to be alert when installing free programs from the internet and keep an eye out for custom installation presentations to avoid any confusion and security risks.
