New malware scam spreading on Facebook

UNDATED -- Annette Stewart spends at least three hours a day on Facebook.

"Before it was a way to communicate with friends, although I still do that, the main reason I go on now is for the games," she said.

Now, she and other Facebook users are on the lookout for a malicious software program called "Koob-face."

"I have heard there is a virus out there if you open it, it will take over your entire computer," said Stewart.

Here's how it works: Cyber-criminals entice you to click on a link, by promising something like an interesting video or a look at sexy photos.

The messages look real, often sent from one of your Facebook friends.

However, you have to download a special program, which is really spyware, that infects your computer then it sends the same bogus message to all your Facebook friends.

"Just one person getting an infection on a social networking site actually opens the door to thousands, if not hundreds of thousands, or millions getting infected," said Jeff Debrosse of ESET Computer Security.

Miles Najera was almost a victim but knew something wasn't right.

"I hadn't talked to that person for a long time. I thought it was weird for him to be sending me a random video or something. I figured it was a virus," says Miles.

Experts say always use an up-to-date browser and keep your anti-virus software updated.

If you do click on the infected link, use a reputable anti-virus software program to clean up your computer.
