What is spyware?

Spyware is defined as a type of malicious software designed to infiltrate a user's device without their consent. Its main function is to monitor user activities, gather personal information, and send that data back to the attacker or a third party. This can include tracking browsing habits, collecting sensitive financial information, and even logging keystrokes.

Understanding the nature of spyware as monitoring software emphasizes the risks associated with it, as it operates covertly, often leading to significant privacy invasions and potential identity theft. Recognizing this helps individuals be more vigilant regarding their online security practices.

The other options describe different software types or applications that do not align with the malicious intent and operational function of spyware. For instance, anti-virus software serves to detect and remove harmful software rather than monitor user activity. Safe online buying tools focus on transaction security rather than data gathering. Legitimate personal monitoring tools typically require user consent and awareness, contrasting sharply with the covert mechanisms of spyware.
