    Yes, I'm starting to see lots of Badtrans.B being caught by my AV gateway.
    Nevertheless, the while.com thing seems to be Magistr.B instead of Badtrans.
    
    Unlike Magistr, Badtrans.B seems to have a fixed pool of random recipients,
    subjects and attachment names. You can check
    http://www.antivirus.com/vinfo/virusencyclo/default5.asp?VName=WORM_BADTRANS
    .B&VSect=T for further details.
    
    Cheers
    
    Fernando
