Actually I am pretty sure that Luis did send the virus.  I deleted his message before it opened and I didnt get teh virus (thanks whoever posted that warning, i could kiss you <smack>).  We arent blaming Luis.  Virus' spread without the user knowing it.  The email from him that I recieved DID have an attachment.  I got rid of it and havent had a problem and am not receiving weird emails.
Take care
