Adware presents pop-up/pop-under ads that are displayed when the main product is not running or that do not appear to be connected with the product (such as pop-under ads while web browsing). These ads may or may not be targeted, and are not displayed within the form of an ad-sponsored application. Adware is often installed along side other 'free' programs that provide file sharing (P2P), clock synching, or weather reports, amongst other functions.
Anti-Spy helps you find these types of programs and lets you decide which to remove and which to keep. For specific details on why some applications are included in the scan results, please read about the criteria.
