It’s a later news that a new worm is spreading via MSN messenger since May.5. It sends out the message about the animation of Bush in Spanish,such as “mira esta animacion de bush :P”, and a file “bush.exe” will be downloaded from a link. These links seem to have been closed now. AV vendors have already detected it.
