3.1.4 Spyware


Spyware is software that can display advertisements, collect information about you, or change settings on your computer, generally without appropriately obtaining your consent. For example, spyware can install unwanted toolbars, links, or favorites in your web browser, change your default home page, or display pop-up ads frequently.

Some spyware displays no symptoms that you can detect, but it secretly collects sensitive information, such as the websites you visit or the text you type. Most spyware is installed through free software that you download, but in some cases simply visiting a website results in a spyware infection.

Spyware gathers information on you to pass on to marketers or intercepts personal data such as credit card numbers and makes them available to third parties.
