It's a holiday weekend in the US, the perfect time thinks one virus writer to launch a fast-spreading attack across Facebook. Anti-Virus company Sophos describes it's method. It begins with an all too-tempting message from one of your friends' feed indicating that they "like" a link with one of the following messages:

"LOL This girl gets OWNED after a POLICE OFFICER reads her STATUS MESSAGE."
"This man takes a picture of himself EVERYDAY for 8 YEARS!!"
"The Prom Dress That Got This Girl Suspended From School."
"This Girl Has An Interesting Way Of Eating A Banana, Check It Out!"
Clicking on the link will instead take you to a blank web page with this simple message:

If you click on the window to see the content, nothing will appear. Instead your profile will be tricked into publishing that you "like" the page with the same teaser message to your friends.
Sophos says the malicious code working within that blank page is Troj/frame-ET.
While there is no real damage taking place here initially, it's important to still remove the results if you've been hit. Make sure to:
Delete the messages the attack has added to your news feed. (Go to your Wall, position your mouse to the right of the message and click on "remove")
Remove the link and page from your Likes. (Click on the Info tab on your profile, look under the "Likes and Interests" section.
