What does spyware mean?
Spyware is software that secretly observes or records information about a person using a computer, phone, or other digital device. It may monitor browsing, capture keystrokes, record screens, track location, or gather personal data and send it elsewhere. Unlike ordinary tools that users knowingly install to perform a visible task, spyware is associated with hidden monitoring and a lack of consent, so the term generally carries a strongly negative and sometimes legal connotation. Security programs, technology journalism, and public-awareness campaigns commonly use the word when discussing infections, privacy violations, and unauthorized tracking. Although spyware is a form of malware, it is distinguished by its central purpose: gathering information about its target. Avoiding suspicious downloads, keeping software updated, and scanning devices are common ways to reduce exposure to it.
nounSoftware designed to gather information about a user or computer without the user's knowledge or consent. It may record browsing activity, capture keystrokes, or collect other personal data.
- Malicious software that secretly monitors a user's computer activity and collects personal information.
- Any software used to track a person's online activity, location, or communications without their knowledge or consent.
"The company removed the spyware after security researchers discovered that it was tracking users' activity."
"A routine security scan detected spyware on the journalist's laptop."
"The guide explains how to remove spyware and reduce the risk of having personal information monitored."
The usual plural is uncommon because the word is normally used as an uncountable noun or with singular modifiers, as in “remove spyware.”
"The report warns that several spywares can install themselves without the user's permission."
Spyware turns a personal device into an invisible observer, often recording what its owner does online without permission.

Where does spyware come from?
The word combines “spy,” from Old French espier and ultimately Latin specere, meaning “to look,” with the suffix “-ware,” which names kinds of software or technology. The suffix was widely used in the late 20th century for computer programs, and “spyware” developed as a term for software that secretly gathers information. The older word “spy” and related forms such as “espionage” share the same historical root concerned with watching or observing.
How spyware is actually used
The term is commonly used for secretly installed software that collects personal information or reports a user's activity. It is also sometimes used more broadly for programs that perform unauthorized tracking, even when their installation does not involve a traditional computer virus.
