Spyware is a type of malicious software that is designed to secretly gather information from a computer or device without the user’s knowledge or consent. This information can include personal data, browsing history, and login credentials, which can then be used for nefarious purposes such as identity theft or targeted advertising. Unlike viruses or worms, spyware does not usually cause direct harm to a computer, but it can significantly compromise the user’s privacy and security. It often enters a system through deceptive means, such as bundled with legitimate software or disguised as a helpful tool, making it difficult to detect and remove. To protect against spyware, it is important to have reliable antivirus and anti-spyware software installed and to be cautious when downloading or clicking on unfamiliar links.
