    I do believe it is not Migmaf, but Download.Trojan.PSK, which downloads
    an IRC bot. Symantec's description is too skimpy - I guess they kept it
    generic in case the same trojan code is distributed using a different
    message or method.

    McAfee has the most complete posted description I've seen so far. They
    call it Downloader-DK.
