One of your friends has invited you to Facebook. After you sign up, you’ll be able to stay connected with friends by sharing photos and videos, posting status updates, sending messages and more.
The email also tries to mimic the Facebook book layout to make it look more genuine.
The attached ZIP file has the name Your_Friend_New_photos-updates_id876011626.zip (number will change) and contains the 60 kB large file Your_Friend_New_Photos-and-Updates.jpeg.exe.
The trojan is known as BackDoor.Andromeda.22, Troj/Zbot-CMV, WORM_GAMARUE.CI, W32/Falab.J.gen!Eldorado.
