So the topic is a little misleading, because I know that a Mac can't be affected by a PC virus. But can you still get one? My aunt bought a MacBook Air and they wanted her to install Norton Anti Virus (it's garbage I know) on it because they told her that a Mac can still get PC viruses and pass them to another PC computer. Is that true? Or are they just trying to prey on people who don't know much about computers? I also own a MacBook Pro and it's my first Mac, so I'm learning some of the basic things as I go. Thanks.
