How Adware Works

A man posting a very large bill poster with the word 'now' in big red letters.

Adware spies on users and tries to display adverts based on a user's browsing habits. The software will examine words typed by the user into search engines and also the type of web pages a user visits. The software will then display adverts that will be of interest to the user.

Note: This type of advertising should not be confused with legitimate advertising that commercial interests pay for to appear on popular web sites.
