Types of Spyware

Spyware is cunning and sometimes vicious software that gains access to your system without permission. It can extract secure and private information from you, making you vulnerable to Internet crime and theft. Typically spyware is categorized in two ways- as commercial or as domestic. Domestic spyware is that which is installed by a computer user. A user might do this to keep tabs on those operating within the network. This is how employers monitor employee's activities etc. Sometimes parents use Domestic spyware to monitor children's activities. Police departments sometimes use it to investigate potential criminal activity. Commercial spyware is
that which other sources, like companies looking to sell products, use to track your Internet habits. They use this information to target marketing to you. This is a lucrative tactic for advertisers, but is an infringement on your privacy as well, according to some opponents.
