While advertisingsponsoring is a common way to publish and promote a product for free,
some software advertising systems do more then just showing static banners, they make secretly use of your internet connection to, for example, retrieve new banner ads from a third parties server or send various information about you.This information is collected and sold to third parties.
Because of the unobviously, secretly behaviour of these systems, they are also called advertising trojans.


Most of these systems are installed with a (often popular) host application, which may or may not work without the snoopware components installed.Some attach themself to your browser, some are completely invisible.

Ad-aware scans your system for known spyware components and lets you safely remove them.
