Spy programs are software that gathers personal information without consent and may share it with third parties. They include system monitors, Trojans, adware, and tracking cookies, and can cause unwanted computer activity, high disk usage, network traffic, application freezing, boot failures, and crashes. People can help prevent spy programs through anti-spyware software, using different browsers than Internet Explorer, firewalls, web proxies, and only downloading programs from trusted websites.
