Malware/Spyware/Adware all mean the same thing – it’s unwanted software that causes harm to your computer by consuming system resources, tracks your Internet activity, provides a backdoor in to your computer, and/or takes over functionality of your machine. Toolbars, screensavers, custom cursors, games, shady websites, file sharing programs, etc are all common causes of infection. Malware is similar to a Trojan in some ways.
