adware(1) (AD supported softWARE) Free software supported by advertising messages. The ads may be targeted to the individual based on key words entered into search engines and the types of websites the user visits. See freemium and adserver.
(2) (ADvertisementWARE) Also called "pitchware," adware is software that periodically collects the user's browsing behavior in order to pop up targeted ads on the computer. Adware often accompanies a program the user purposely downloads, and although it may be clearly indicated during the install procedure, novices generally keep clicking Next without reading the dialogs. If the adware is installed without disclosure, it is considered "spyware." If the disclosure is in the end user license agreement (EULA), it is still spyware because people click "I agree" without reading it. See contextual marketing, popup ad, PUP, spyware, parasite and wares.
