If you're on facebook, read this:
You WILL get an inbox message from someone on your friends list. It will be something about a video. It could be "Look at this awesome video" or "I found an old video of you!" or something. If you open it, and you use the windows operating system, congrats on the virus that you just downloaded. Also, all of your friends will get the message from you, so it can spread quickly. Sweet, huh?
I'm just sayin'.
