Advertisements aren’t too bad in general, right? You usually see them as commercials while watching TV or as billboards when you head to work.

Adware is similar, but the ads it generates are the worst of their kind. This malicious software gets into your computer under the guise of an application which you’ve recently downloaded.

It then follows you around as you browse the Web and takes notes of sites you visit, purchases you make, and services you use. In turn, it relentlessly bombards you with ads on your browser, computer desktop, and everywhere else it can — outright annoying!
