Facebook worm

Koobface, the Facebook worm that takes over computers by spreading through the social network, is back in a new form. The newly tweaked Facebook worm works like its predecessor, only with an updated look and code that might not be caught as quickly.The new variant, discovered by researchers at Trend Micro, poses as a YouTube page. It’ll even display your name and photo from Facebook to give a nonthreatening appearance to unsuspecting users.
Koobface tricks you into following a link that looks like it’s from a friend. It’ll usually look like a link to a video of someone you know. Once you open the link, though, you’ll be told you need to download an update to your video player. That update is actually the Facebook worm threat in disguise.Once you agree to install the software it offers, the Koobface worm will take over your computer and hijack your Facebook account. It’ll then live up to its Facebook virus reputation by sending messages to your friends and attempting to infect them.
