Give some Overview of Spyware?

Spyware is one type of malicious software (malware) that collects information from a computing system without your consent. Spyware can capture keystrokes, screenshots, authentication credentials, personal email addresses, web form data, internet usage habits, and other personal information. The data is often delivered to online attackers who sell it to others or use it themselves for marketing or spam or to execute financial crimes or identity theft.

Software installed after the user has read and agreed to a clear privacy policy or to an End-User License Agreement (EULA) that describes the software’s data collection activities does not meet the definition of spyware. It is your responsibility to carefully read such polices and agreements to make sure you understand and agree with their terms.
