LESSON 410
STOP SPYWARE FROM AUTOMATICALLY INSTALLING Windows and its browser program, Internet Explorer, works behind the scenes to make things as easy as possible for you. The theory? The less you have to do, the easier it is to use Windows and the more likely it is you won't get into trouble. Most of what goes on behind your monitor is set up to work by default. But some of the default settings can get you into trouble. For Example, the Automatic Install can let a spyware install itself without you even knowing it. Here's how to prevent this from happening. From within Internet Explorer, click on Tools and then on Internet Options. Now click on the Advanced tab, and under the Browser section, remove the checkmarks from the boxes next to Enable Install On Demand (Internet Explorer) and enable Install On Demand (other) to prevent malicious spyware programs from automatically installing themselves without your knowledge. Now your computer is that much safer on the Internet.
