What type of software is spyware primarily designed to do?

Spyware is primarily designed to collect information about users secretly. This type of software operates in the background, often without the user's knowledge or consent, and can gather a wide range of data including browsing habits, personal information, login credentials, and other sensitive data. The key characteristic of spyware is its stealthy nature; it does not alert users to its presence, making it particularly concerning for privacy and security.

The primary function of spyware is to monitor user behavior and transmit this data to third parties, which can lead to various privacy violations and security risks. Unlike other forms of malicious software that may seek to cause damage or disrupt service, spyware’s main goal is to gather information that can be exploited for financial gains, targeted advertising, or identity theft.

In comparison, other types of software mentioned have distinctly different purposes. Some may aim to infect and damage systems (such as viruses), optimize system performance, or assist in data recovery, but they do not have the covert information-gathering focus that defines spyware.
