(Kim Komanso) The malware in question is called "Zeus." In most cases, it looks like a funny or shocking video one of your friends posted. It may be posted on their page or in a message to you.

Once you click the link to the "video," it will tell you that you need to update the player to watch the video.

When you try to do that, you download the virus. When you click the "Play" button, you're actually clicking "Like" on the virus page. It will spread the link to all of your friends to try to infect them.

Don't fall for it. If you get a message from your friend, ask them if they meant to send it. In most cases, they won't even know that they are spamming you.

You can also search the title of the video in question on Google or YouTube. If nothing turns up, you'll know the video is a scam.

Fake videos are a popular Facebook scam, but they're not the only one. I know three more you need to watch out for. I'll tell you what they are and how to avoid them in this must-read tip.

Don't forget to 'Like' my page on Facebook, as well. I'll give you plenty of security ideas all of the time. I also post fun and funny videos I find from all over the Web.
