Okay, pard'ner. Let's lay it on the line. When you hear people talking about Internet security, they can be talking about one of two things. One type of security protects your computer from picking up bad programs from the Internet. These programs, also known as v…v…viruses, can hurt your trusty machine or make it go berserk. I'll be talking about this type of security in this unit so pay attention, okay? The other kind of security protects the little ones from content that is…ahem…questionable, or not in the best of taste. We'll talk about this type of security in the next unit.
