Which of the following describes the primary purpose of spyware?

The primary purpose of spyware is to gather personal information from users. Spyware is a type of malicious software designed to collect data about a user's activity without their knowledge or consent. This can include various types of personal information such as passwords, credit card numbers, browsing habits, and even sensitive personal communications.

Spyware often operates in the background, making it difficult for users to detect its presence. The data collected can be used for various purposes, including identity theft, unauthorized financial transactions, and targeted advertising. Understanding the function of spyware is essential for maintaining personal data security and privacy online.

In contrast, other options do not relate to the intent or function of spyware. For example, deleting temporary files is typically a maintenance task meant to optimize system performance, and enhancing graphics falls under software that improves user interface experience rather than espionage. Providing security against intrusions is the role of security software like antivirus or anti-malware applications, which is the opposite of what spyware aims to accomplish.
