    I can't believe some moron actually wrote a virus with LISP.
    I guess the moron just wanted to be the first to do it.

    Yes, the last message I posted was the fix. Have you tried fixing it with anti-virus software? If so, what software?

    What antivirus software are you using? We are using Trend and it detected it too. But finding it is not the issue, how do we get rit of it?

    Here is some instructions from Symantec for deleting the virus. But this is not acceptable when I am dealing with 250 users. We need a better solution.

    1. Disable System Restore (Windows Me/XP).
    2. Close all running instances of AutoCAD.
    3. Update the virus definitions.
    4. Run a full system scan and delete all the files detected.
    5. Remove the entry added by the virus from acad.lsp in AutoCAD's Support folder (optional).

    That's exactly what we've been doing for the last 5 months, but that won't resolve the problem permenately right?

    I can not answer that because I can not really imagine what happens.

    I have reading the code that lance posted and you can stop the function that do the nasty writing by adding this (setq writeapp nil ) last in your startup routine.
    You can also erase all acad.lsp that is not in AutoCADs search path.

    The program read line by line from (findfile "acad.lsp") or (findfile "acadapp.lsp")
    and write line by line to "current drawing location" acad.lsp
    that acad.lsp is executed when you open a drawing in that location, kind of clever...
    If your system acad.lsp is in a network read only location you can use Windows Search File "acad.lsp" and erase all that is not in AutoCADs search path.

    Open (findfile "acad.lsp") and (findfile "acadapp.lsp") in AutoCADs search path
    and remove the entry added by the virus.

    maybe that will do the trick.
