A new computer virus is making the rounds online, using the Facebook brand to trick unsuspecting users into downloading potentially vicious malware.

The virus arrives as an attachment to an e-mail claiming to be from Facebook. The subject line reads "Facebook Password Reset Confirmation" and purports to be from "The Facebook Team," according to Belgium-based security research firm MX Lab.

The message itself reads: "Because of the measures taken to provide safety to our clients, your password has been changed. You can find your new password in attached document."

But the attachment actually contains a nasty virus called the Bredolab Trojan, which security analysts have been tracking for a while.

Once downloaded, the virus gives the sender complete control of the target computer, allowing cyber criminals to potentially spy on users of the computer or use it to steal personal information or distribute more spam.
