ADWARE

Adware is a type of advertising display software that delivers advertising content potentially in a manner or context that may be unexpected and unwanted by users.
Many adware applications also perform tracking functions, and therefore may also be categorized as tracking technologies. Some consumers may want to remove adware if they object to such tracking, do not wish to see the advertising caused by the program, or are frustrated by its effects on system performance.
