What are Potentially Unwanted Programs (PUPs)?

Potentially Unwanted Programs (PUPs) are software applications that are not classified as viruses or malware but can negatively impact your computer’s performance or user experience. They often come bundled with free downloads or are installed without the user realizing it.

Common traits of PUPs:

  • Bundled software – installed alongside free programs without clear notice.
  • Excessive ads & pop-ups – some act like adware, showing unwanted promotions.
  • Performance slowdown – they may use system resources unnecessarily.
  • Privacy concerns – some track browsing habits or collect data without consent.

Examples of PUPs:

  • Toolbars added to browsers that you didn’t ask for.
  • “Free” optimization or registry cleaners that push paid upgrades.
  • Software that changes your default search engine or homepage.

How to protect against PUPs:

  • ✅ Always choose custom installation and deselect extra offers.
  • ✅ Download software only from official or trusted sources.
  • ✅ Use a reputable antivirus or anti-malware program that detects and removes PUPs.

In short: PUPs aren’t always dangerous like viruses, but they are annoying, intrusive, and sometimes risky. It’s best to avoid and remove them.
