There was another one a while back that sent a message something like "mira las fotos" and then downloaded a program called "foto.exe". You don't need to guess what that was... Many of these msn trojans seem to be targeted at the latin american spanish speaking users. The message tend to interrupt a conversation you're having with a contact to try and trick you into thinking the contact is sendin them, but it's usually spread by the trojan being on your contact's msn program. Personally I don't use msn these days, but when I did I used an open source program called gaim as my msn client.
