Spyware is also known as "adware” or “ data collecting programs”. Spyware are programs that use your web connection to send out your personal information.A malicious software when installed on your computer, may send you pop-up ads, redirect your browser to certain web sites, or monitor the web sites that you visit. If a Web site stores information about you in a cookie that you don't know about, the cookie can be considered a form of spyware.  Even some invasive versions of spyware may track exactly what keys you type.
