CompareItApplication (also referred to as compareitapplication virus, !!compareitapplication!!) is adware and a potentially unwanted program (PUP) that generates pop-up ads across Mozilla Firefox, Google Chrome, Microsoft Internet Explorer, and Apple Safari.

Targeted advertisements can only be produced by the adware if it has access to personal browsing data including all browsing activities, bookmarks, and browser history. The term ‘browsing activities’ covers a wide variety of data such as the webpages you visit, information you submit online (email addresses, telephone numbers), web searches, and more. This information is not only used to produce targeted ads but may also be handed over to third-parties and administered for other email, home, and telephone marketing campaigns.
