It's a program or programs (like Gator for example) that install on your Hard Drive and secretly spies on your computer habits (especially your web habits) and reports them back to a company. Sometimes the spyware is just used for advertising. But in the case of company Doubleclick, they try to attach a face (name, address, email) to your surfing habits. They deny that this is happening, but there is evidence to the contrary.
You may have spyware on your computer without you knowing it.
Download AdAware 5.62 and run it. You will be suprised at how much you already have on your system.
