What’s a PUP (Potentially Unwanted Program) Exactly?
PUP is short for “potentially unwanted program” (sometimes referred to as PUA, potentially unwanted application), even though a better name would be “absolutely unwanted programs”. At best, these programs provide little to no benefit, and at worst, they can be quite harmful to your system. In addition to taking up space on your hard drive, they also slow down your computer, often change settings without your say-so, the list of annoying features goes on and on. While this is obnoxious, the worst part of installing a PUP is the adware, spyware and keystroke loggers that lurk inside. That’s why you should take special care to study and avoid these PUPs!
Examples of PUAs:
As you can see, both macOS and Windows users are targeted by PUAs. A 2020 study also revealed that an average of 11 threats per Mac was registered in 2019. This is nearly double the average percentage per one Windows computer. In other words, it turns out that the average number of threats detected on Macs is not only increasing but it is also surpassing Windows, making macOS more susceptible to potentially unwanted apps that Windows.
According to recent statistics provided by Kaspersky Labs, in Q3 of 2021, 62,577,326 unique malicious and potentially unwanted objects were detected, meaning that this threat continues to evolve.
How Can Unwanted Apps Breach Your System?
Getting a PUP into your PC can be very easy if you’re not careful. Sometimes a useful program will be bundled with “crapware” PUPs you don’t need. While you’re installing the useful program, the wizard will include options to install various programs, some of which are PUPs. They appear under the “Advanced” or “Custom” options of the installation wizard. When you click them, the list of bundled programs should be visible. Be sure to opt out of installing any programs you don’t want.
Despite being considered very unethical in software circles, unwanted programs aren’t necessarily viruses or malware, because they require the user’s permission to be installed. A virus needs to come in through the backdoor, while PUPs are invited through the front gates. That’s why anti-virus programs can’t classify them as a threat and may not remove them. It’s a catch 22; PUPs are almost always bad for the user, but they can’t be banned or considered viruses. The main reason is that bundling programs aren’t inherently illegal or bad.
Note!Not all bundled programs are PUPs. Some of them might even be desirable for the user and even big name companies like Microsoft and Adobe bundle their products. It’s impossible to make a legal distinction between what’s “potentially unwanted” and what plain unwanted. In addition to that, PUP developers would often go to court when an anti-virus program classify their programs as viruses.
What’s the Actual Harm of Potentially Unwanted Apps?
As mentioned beforehand, PUPs can bring on adware, spyware, keystroke logging and other nasty crapware “features”. PUPs can change your browser settings, putting new search engines, home pages and apps that can be a pain to remove, excessive and intrusive ads, popups and banners, and many other forms of annoying advertisement. Adware PUPs usually induce excessive ads, usually of the “one weird trick to lose weight” or “make lots of money just by staying at home” variety. Keystroke logging is a method of stealing personal information by recording everything written on the recorded keyboard, including passwords and codes. Spyware records the user’s actions and online behavior. That information, more often than not, goes to untrustworthy online places.
Who Benefits from PUPs?
PUP distribution can be quite lucrative. As we’ve established, combating PUPs is difficult, so it’s a lower risk endeavor than spreading viruses. Mindspark is a good example of a company that’s almost exclusively devoted to spreading PUPs. QuickPhotoEdit, TestForSpeed(.)com and FromDocToPDF(.)com are just a few recent examples of their many PUP products.
How to Protect Your System from PUPs
As annoying a PUPs can be, their installation can be avoided easily by user vigilance.
Here are a few easy steps you can take to avoid installing PUPs:
- Don’t download programs from Internet ads, pop-ups, torrent trackers, file sharing sites and other unreliable sources.
- Opt out of the setting hidden in the “Custom” or “Advanced” sections when you’re installing a program. You can deselect most PUPs from there.
- Avoid installing programs you don’t need.
- Keep an eye out of any excessive or unusual Internet advertising. These ads can be brought on by PUPs and adware attached to your browser.
- Read the terms and conditions of use when you install any programs.
- Check your installed software regularly and uninstall any applications you do not want or need.
- Install an anti-PUP program. Most security software can’t outright delete PUPs, but some of them can discover and warn the user, so he or she can do it by themselves. Some anti-virus programs have ant-PUP capabilities that are disabled by default, so make sure to turn them on. An anti-spyware program will also do the trick as it strictly watches out for spying components (like tracking cookies).
Remember that even though PUPs can be damaging to your PC, they can’t get into your PC without your permission, so be alert not to give it to them. As always, good cyber-security etiquette can prevent most online threats.
