What is a Potentially Unwanted Application?

Potentially Unwanted Applications, or PUAs, are programs installed in devices that may pose risks on user security and/or privacy. They do not completely state their function and are often installed without your knowledge.

How does PUA behave?

  • Piggybacks (installs itself) to other legitimate programs during installation
  • Displays excessive advertisements
  • Collects information without your consent
  • Exaggerated or bogus notifications
  • Lack of control for users
  • Runs processes that consume computer resources
  • Difficult to uninstall
