====Spyware====
Programs designed to monitor users' web browsing, display [[unsolicited advertisement]]s, or redirect [[affiliate marketing]] revenues are called [[spyware]]. Spyware programs do not spread like viruses; instead they are generally installed by exploiting security holes. They can also be hidden and packaged together with unrelated user-installed software.<ref>{{cite web|title=Peer To Peer Information|url=http://oit.ncsu.edu/resnet/p2p|access-date=25 March 2011|publisher=NORTH CAROLINA STATE UNIVERSITY|archive-date=2 July 2015|archive-url=https://web.archive.org/web/20150702143115/http://oit.ncsu.edu/resnet/p2p|url-status=dead}}</ref> The [[Sony BMG copy protection rootkit scandal|Sony BMG rootkit]] was intended to prevent illicit copying; but also reported on users' listening habits, and unintentionally created extra security vulnerabilities.<ref name="russinovich" />
