It is a classification for software that can be used to show advertisements or gather user data that can be used for marketing purposes.
Adware is usually installed with the use of software engineering by bundlers or as an option for some free software. Some adware have the possibility to intercept and modify Internet communications, and can collect personally identifiable information (PII) that is used to create a user profile, in order to display targeted advertisements. These ads can be shown in the form of pop-ups, pop-under, text links or in-text ads, banners or even full page ads. Many adware applications can only be perceived as “annoying” while others can pose a real threat to user’s personal data as some adware producing companies even state in the End-User License Agreement (EULA) that any collected data can be sold to third parties.
