If you have only one computer at your home, yours, but you have other members of your family living there. Chances are they will get on your computer when you are not around. To most of us who do a lot of work on your computer, your computer is like a women's purse. Not to be touched. However, not everyone sees it that way. So let's say, you are working on a project on your home computer, and you have everything just as you want it, but when you get back to it in a couple of days, things have changed. Nothing is how you left it. Now, after a thorough investigation and lengthy questioning of your family members you still don't have a clue as to who changed anything on your computer. "I didn't do it!" is usually the guilty culprit at my house, and they are sneaky aren't they?
