Adware is software that companies use to track your Internet browsing activities. Companies that track your online habits often sell this information to marketers who then hit you with targeted advertising—ads that match your browsing interests and would most likely appeal to you.

Advertisers are delighted when they acquire such valuable marketing information so easily; in the past marketers had to bribe you to learn your preferences through contests, registration surveys and the like. Those methods of gaining your personal information still exist, but in those cases you have the power to read the fine print to learn the fate of your data and so could choose to consent or refuse. Gaining your preferences by stealth using software spies is far easier and offers a much more complete picture for the marketing industry; as a result, adware is everywhere.

Is it Dangerous?

At the very least, adware is a nuisance—slowing down your computer, filling your hard drive with useless gunk and marking you as a target for enterprising advertisers. Beyond intruding on your privacy, spyware can be used as a tool to perpetuate crimes, such as identify fraud. Go to our Basic Spyware Removal to learn how to effectivley scan your computer.
