AutoCAD *virus* ????

    I am a networking consultant working with a large architectural firm.
    They have run into an AutoCAD problem that I have never heard of
    before and don't have the foggiest idea where to begin. I haven't
    worked with CAD -especially AutoCAD- in years so I thought I'd post a
    summary and see if anyone has heard of this one.

    Although I've never heard of a virus affecting CAD files, this
    phenomenon sounds almost viral in nature. The problem seems to be
    spreading around the office. First it was one person, then their
    project team now loads of people.

    The first symptom, which appeared a few days ago, was that the XREF
    dialog box would not appear. When "XREF" is entered at the command
    line, the resulting prompt is "Specify block to insert." The second
    problem that appeared today is that the affected users can not explode
    any blocks at all. No error is reported, the block just remains the
    same.

    Some users are still fine but once affected (infected?), they stay
    that way.

    Any and all help would be appreciated.

    Thanks for your help Paul,

    We seem to have a rogue acad.lsp file that is propagating into all of
    the project folders on the network. It is small (3kb) and we don't
    know where it is coming from. Below is a sample of the first 10 lines
    or so:

    (defun
    s::startup
    (/
    old_cmd
    path
    dwgpath
    mnlpath
    apppath
    oldacad
    newacad

    Prepending XREF or Explode with a period (e.g., ".explode") results in
    the command working as designed. Any idea what could be generating
    the bad .lsp file?

    Thanks again,

    Bruce
