Spyware is a relatively new kind of computer threat not yet covered by common applications that concentrate solely on viruses. Spyware silently keeps track of all of your surfing behavior in order to create a marketing profile of you that, without your knowledge, is given to the makers of the spyware and then sold to marketing strategy firms who will then be able to make a profit and form a better ad campaign.

How will I know if I have spyware on my computer? The first sign that a computer is infected is when the Internet browser pops open, and suddenly a million pop-up advertisements show up on the screen. Another warning sign appears when your Web browser’s home page is different from the original. There could also be new pages added unexpectedly to your Favorites folder. Many more negative side-effects are brought on by Spyware. Possibly the worst will happen when your computer is no longer able to run a program, nor get directly linked to a website.
