MSN Messenger trojan?HELP!

[orcmeister]

Hi my brother accepted a "picture" file from his msn messenger from a friend which turned out to be a .zip file...im assuming its a trojan it keeps spamming new conversations and sending the file over and over to the contact list... the message sent says something like "hey can i add this picture of us to facebook?" I ran a virus scan which found nothing...any help would be appreciated.
thanks

Hello.

Please see the stickied procedure for this forum: "BEFORE you POST"(READ this Procedure BEFORE Requesting Assistance)

Copy/paste the HJT log and result of the on-line anti virus scan into a new topic, I will close this one as helpers look for zero response.

Regards.
