What Is Adware Software?
Adware is hidden software code that displays advertisements on the user's computer. It may be part of a downloaded software program. Usually there is no advance warning that software contains adware, so the user may be taken by surprise to see advertisements pop up on his screen.

Benefits
-
Software producers distributing free programs or on a trial basis may try to get some revenue with adware. This lets users try out programs at no expense.
Effects
-
Hopefully, the continual display of advertisements is only a minor annoyance, but sometimes they become so intrusive as to affect work.
-
Considerations
-
The code that generates adware advertisements is an integral part of some software. It can only be removed by purchasing a legitimate copy or removing the software.
Misconceptions
-
Adware is not spyware. Adware is the legitimate display of ads that accompany downloaded software on your computer. Spyware hides on your computer and tracks your actions and surfing.
Warning
-
Supposedly, adware does not report computer activities to other people or organizations. However, since it is not under the control of the user, it could do this without notice.
Examples
-
Application software such as Eudora's free version uses adware until the user upgrades. AOL Instant Messenger may use adware.
