What is Adware?
Adware, or advertising-supported software, is any software package which automatically plays, displays, or downloads advertisements to a computer after the software is installed on it or while the application is being used. Some types of adware are also spyware and can be classified as privacy-invasive software.
Advertising functions are integrated into or bundled with the software, which is often designed to note what Internet sites the user visits and to present advertising pertinent to the types of goods or services featured there. Adware is usually seen by the developer as a way to recover development costs, and in some cases it may allow the software to be provided to the user free of charge or at a reduced price. The income derived from presenting advertisements to the user may allow or motivate the developer to continue to develop, maintain and upgrade the software product. Conversely, the advertisements may be seen by the user as interruptions or annoyances, or as distractions from the task at hand.
Some adware is also shareware, and so the word may be used as term of distinction to differentiate between types of shareware software. What differentiates adware from other shareware is that it is primarily advertising-supported. Users may also be given the option to pay for a “registered” or “licensed” copy to do away with the advertisements.
Some adware can also be classified as spyware, a type of malware (malicious software) which steals information. For example BonziBUDDY, an application marketed as an “Intelligent software agent”, corrupted many of the user’s system files, forcing the display of many obscene advertisements (composed mostly of infected Flash coding); these and the main application logged browsing details and sent them to various third parties. Adware applications can also be classed as other forms of malware: for example as an adware Trojan horse (which disguises itself as a trusted application—e.g. Microsoft Word—and displays infected advertisements such as “download XP service pack 4, great bargains, latest update”). and so, to remove these kinds of adware, go to tech support sites.
