What is the primary function of spyware?

The primary function of spyware is to monitor user activity without detection. This type of malicious software is designed to secretly gather information from a user's computer, which can include browsing habits, keystrokes, and personal information such as passwords and credit card numbers. The covert nature of spyware allows it to operate unnoticed, making it a significant threat to user privacy and data security.

Spyware is often used to collect sensitive data that may be sold to third parties or used for identity theft. Its effectiveness relies on remaining hidden from the user as it silently tracks online behavior and activities.

Other functions mentioned, such as speeding up computer performance, preventing unauthorized access to data, or automatically updating system software, are not characteristics of spyware. These functions pertain to legitimate software or security measures, whereas spyware is fundamentally designed for surveillance and data collection without the user’s consent.
