7 7 Windows Defender You can find all kinds of interesting and useful things on the Internet. Most Internet users will occasionally take advantage of one or more of the many free programs available. However, many people don t realize that some of these applications can contain components that gather information about users. For example, you might download a handy little program for keeping track of your household budget that secretly monitors your surfing behavior. Information about your visits to stores is silently sent to the software s creators without your knowing it. They can then pester you with advertisements and annoying pop-ups about certain products. Programs that monitor your computer activities in this way are called spyware. Before the introduction of Microsoft Security Essentials, the program Windows Defender was widely used to detect and remove unwanted spyware from a computer. Since Microsoft Security Essentials can also detect and remove spyware, Windows Defender is automatically disabled with the installation of Microsoft Security Essentials. Would you prefer to use Windows Defender? Perhaps you have a different anti-virus program other than Microsoft Security Essentials already installed. In that case, you can use this PDF guide to learn more about Windows Defender. In this booklet, you will learn how to: download and install Windows Defender; scan your computer; adjust scan settings. Please note: In order to perform all of the necessary actions described in the following sections, you will need to have administrator privileges. Otherwise you will not be able to make the required changes and a dialog box from Windows will appear indicating that there is a problem with permissions. If that is the case, you can just read through the relevant section. Please note: In this PDF guide, you will find instructions covering the various versions of Windows. This means that sometimes the screenshots you see in this guide may not be exactly the same as what you see on your own screen. Any differences that may occur will be noted in the text.
