Step 2: Know where spyware comes from

Spyware most commonly enters a computer one of two ways: silently, through a Web page, or bundled with another software program.

Spyware most commonly enters a computer one of two ways:

  1. It's loaded silently via a Web page, often through a pop-up window or a hidden frame. No warning is given that the page is attempting to install a program, unless the Web browser is specifically designed to warn the user of such things. (The first edition of Internet Explorer 6 and all previous versions of Internet Explorer were vulnerable in this fashion.)

  2. It's bundled with another software program, often as a way of generating advertising revenue to support that program's development.

The first of these two vectors is by far the most broadly used -- especially in organizations where desktops have not been correctly secured and browser plug-ins can install with impunity. The second isn't as widespread, but still popular, since you may install what you think is a free application and only find out later that it's harboring spyware.
