Why spywares are so common around the internet? Well there are certain companies that make money just by one click of a user, even though that computer user is not spending a penny. The reason behind is that these companies put their advertisements over different websites, websites that are being run by individuals. The reason these individuals give space to the advertisements of the company is that the owner of that website himself or herself makes money just by putting that ad on their website. The companies want their products to get famous, known or to get more clients so they put up their advertisements to attract customers. In the Internet marketing business everyone wins whether they are a company advertising their product or the owner of website advertising that companies ads.

Some of the major, well-known softwares act as a spyware too like Kazaa, Bonzi Buddy, iMesh, Grokster etc.
