Potentially unwanted programs (PUPs) are pieces of software that get bundled with other free downloads and installed on a user’s device without their knowledge or consent. Though not inherently malicious, PUPs can negatively impact system performance, slow down devices, and irritate users with unwanted advertisements and popups. This comprehensive guide will provide readers with a deep understanding of PUPs, how to identify them, safe removal methods, and tips to avoid encountering them in the future.




What Are Potentially Unwanted Programs?
Potentially unwanted programs (PUPs) are software applications that are not viruses or malware, but still exhibit undesirable or suspicious behavior. PUPs typically come bundled as an additional component within free software downloads or other programs. The main objective of PUPs is to generate revenue for their developers through advertisements, collecting user data, or upselling paid versions of software.
Some key characteristics of PUPs include:
1. Bundled with Downloads
The primary method PUPs spread is by bundling themselves with otherwise unrelated free program downloads. Often these additional programs are optional during installation but selected by default, resulting in many users unintentionally installing PUPs.
2. Generate Advertising Revenue
Many PUPs contain advertising modules that continually display popups, notifications, and other intrusive ads. Developers earn revenues based on user engagement with these ads, which incentivizes designing programs that are difficult to block or disable.
3. Collect User Data
PUPs harvest user data including browsing history, search queries, and system information. This data gets sold to third parties for targeted behavioral advertising or analytics.
4. Deceptive Upselling Tactics
PUPs frequently employ dubious tactics to convince users to purchase paid versions of programs in order to unlock additional features or remove restrictions. These upsells provide additional revenue streams.
5. Reputational Damage to Host Programs
The inclusion of PUPs with downloads leads many users to leave negative reviews of those host programs, damaging their reputations. However, the host programs may not actually be low quality themselves.
6. Difficult to Remove
PUPs often lack clear uninstall procedures compared to typical software. Many deliberately use complex removal methods or leave behind configuration files, registry keys, and other traces after uninstallation.
So in summary, the core aspect of PUPs is that they provide little practical value for most users, yet employ aggressive and deceptive methods to profit off those users through ads, data collection, and manipulative upselling tactics.
What Do PUPs Do?
Now that we’ve defined what constitutes a potentially unwanted program, let’s explore the most common behaviors and issues caused by PUPs:
Display Intrusive Advertising
The majority of PUPs contain ad modules that constantly open popups, display banner notifications, inject ads into webpages, and more. These come in many forms such as notifications prompting users to scan their device, fake error messages, offers for unnecessary software, and warnings about nonexistent issues.
Run Constant Background Processes
PUPs typically run continual background processes to display ads, connect with advertising networks, collect system data, and listen for triggers to display more ads. This consumes device resources, resulting in reduced performance and sluggishness.
Track Browsing History and Usage Data
PUPs harvest private user information such as browsing history, search queries, and any input into forms. This data gets sold to third parties for targeted advertising or analytics, often without the user’s consent.
Install Additional Software
Some PUPs will install secondary utilities that also display ads, monitor usage, or have other purposes. They may install browser extensions, plugins, or other software without notifying the user or obtaining their consent.
Bundle with Free Software Installers
As mentioned previously, bundling with freeware and shareware installers is the primary distribution method for PUPs. They get selected by default during installations, tricking users into accidentally installing PUPs.
Modify Browser Settings
To ensure their ads and scripts load properly, some PUPs alter browser settings like the default search engine, home page, and proxy configurations. This facilitates injecting more ads and tracking user behavior.
Resist Removal Attempts
PUPs are designed to be difficult to fully remove, often leaving behind configuration files, registry keys, processes, or other traces. Some deter uninstallation by displaying misleading warning messages about the risks of removal.
Upsell Unnecessary Software
PUPs frequently try upselling paid software that claims to speed up devices, optimize systems, recover lost files, fix nonexistent issues, etc. These programs have little real utility but generate revenue from users tricked into buying them.
So in summary, PUPs negatively impact system performance, display intrusive ads, harvest private user data, and resist removal using deceptive tactics focused on earning money rather than providing value to users.
How to Identify If Your Device Has PUPs
PUPs exhibit certain behavioral patterns and other indicators can help identify their presence on a device. Here are some signs to look for when determining if PUPs may have infected your computer or mobile device:
Increase in Popup Advertisements
Frequent popups, banner ads, notifications, and other advertising appearing randomly likely indicate adware PUPs installed and running in the background. Legitimate programs generally won’t constantly barrage users with ads.
Sluggish Performance
The combination of continual background processes, apps, unnecessary services, and other components of PUPs bog down devices, resulting in sluggish speeds, long load times, and laggy responses to user actions.
Unknown Browser Extensions
Check your web browser’s add-ons and extensions – any unknown or unrecognized ones could be installed by a PUP payload to display ads or collect browsing data.
Unfamiliar Background Apps
Review the list of installed applications on your device, laptop, or desktop computer. Any unfamiliar or generic-sounding apps may be unwanted programs bundled by PUPs.
Suspicious Background Processes
Use Task Manager or Activity Monitor to check for any peculiar processes using high CPU or RAM – unfamiliar names suggest PUPs running advertising and tracking modules.
Unusual Browser Homepage/Search Engine
If your browser’s homepage, default search engine, or new tab page got switched without your knowledge, PUPs may have modified your settings to display ads or intercept searches.
Missing Uninstall Options
Attempting to uninstall suspicious programs only to find missing options or buttons indicates PUPs deterring removal. Legitimate software always provides simple uninstall methods.
Unrecognized Logins or Activity
Check account activity – logins from unrecognized locations or devices could mean PUPs harvested and sold your credentials or other sensitive information.
If you observe any of these signs, your device has likely been infected with potentially unwanted programs that should promptly be removed. Catching PUPs early before they cause excessive damage is key.
