Stands for “potentially unwanted program.” A program (or bundle of programs) which may come bundled with software the person downloading it was looking for. The PUP component may include unnecessary offers, add-ons, deals, adverts, toolbars, and pop-ups, all of which may be entirely unrelated to the functionality of the sole wanted program.
