How to clean acaddoc.lsp virus from your pc

Buy LspCleaner

This article is obsolete. Check our lisp removal software Lisp Cleaner.

Actually acaddoc.lsp is not a virus, it is a worm depending on autocad lisp routines. All it does is copying itself in every folder you open a drawing. I created a lisp routine to clean all the existences of the worm from lsp and mnl files located at the autocad support folders.

Follow these steps to get rid of this worm:

  1. Download the routine:
    Lisp file is removed. Please use Lisp Cleaner to get rid of this worm.
  2. Load the lisp file using APPLOAD command
  3. The lisp file will run automatically and it will clean all the existences of the worm in your support folders.
  4. Run an antivirus or a cleaner to get rid of “acaddoc.lsp” files. Normally cleaner routine installs a simple routine in your acad20XXdoc.lsp file which automatically clean those files but i recommend cleaning all the viruses with an anti-virus first. You can also download del-acaddoc.bat (link removed) dos batch file to clean all your drives manually. Run this batch once and it will delete all acaddoc.lsp files on your system.

NOTE: If any of the infected files in your Autocad Support folders are READONLY the cleaner won’t be able to clean those files !!

WARNING: This routine will install a routine to delete “acaddoc.lsp” files. If you somehow use acaddoc.lsp files remove the following lines from your acad20xxdoc.lsp starting with:

(setq acaddocfix t)
;;; ^^ ACADDOCFIX STARTS HERE ^^


Please contact me if you see an error.
Cheers!

    Worked flawlessly in an office of 20 ppl and of AutoCAD & Civil 3D versions ranging from v2002 – v2010…

    acaddoc.lsp was not deleted automatically so I ran a search on each pc to delete it manually. That’s normal right?

    What’s not normal is that the antivirus (AVG free) didn’t raise any alarm for the worm, even though in a Microsoft site it is stated that AVG has categorized the worm:
    ‘ACAD/Bursted.B (AVG) ‘

    Thanks again!

      Oh cool, nice to know it works. And yes it doesn’t delete previously generated acaddoc.lsp files in case.
      This worm is a real trouble because it uses a really important file as host.
      Most of antiviruses don’t delete those files in case they have important user scripts.

    Dear Brother.

    I m a victim of virus autcad too. I really need help. Of course, i have follow what u describe upper but the main hamper, it still work. I mean i can’t remove it from my pc.

  • ankita Nov 11, 2010

    hey thanks so much for the information im experiening the same problem. but can u help me with your 2nd step where doi locate the appload command? in autocad or in windows.. please help me out seen its gettin crazy in my laptop now

    • metin şaylan Nov 26, 2010

      Just enter it to the command line “APPLOAD” and it will show you a dialog to locate the script. Alternatively you can put the fixer script to the support folder and type (load "acaddocfix_1.6") to load it without dialog.

  • luai Nov 30, 2010

  • Subhash Gandha Jan 25, 2011

    Thank u very much dear metin şaylan. I am relaxed due to your given solution. This virus (?) was embarrasing me since last 15 days. It blocks the network drive. All the files on my network were became read only and no editing/saving was possible form my PC to my network comouter. I have run your two files and the problem is solved.
    Thanks. Subhash (25th January, 2011.,India)

    Selam Metin Saylan,
    thanks you for sharing the file to kill those worm. After 2 days feels like all memory and cpu resource sucked by uncertain things, I realize that acaddoc.lsp is the trouble maker. And then, I find your site.

    Again, Many thanks.
    greets from Bali

  • Douby Jun 14, 2011

    Hi Metin,

    Thanks for the help! The routine worked great for me. I had tried deleting all the infected files by myself but I couldn’t find them all, and you came to save the day.
    Keep up the good work!

    Cheers

  • Peyman Jun 15, 2011

    This .lsp file worked on one installation of Autocad 2011 but it crashes on autocad 2011 MEP.

  • kimo May 2, 2012

    i have acad.lsp file it copy it self eache time i open drawing and i can’t open cad directly i must open drawing to open autocad and i tied to use your solution but it didn’t work what should i do .
    thanks

  • Tities Guritna Oct 20, 2012

    It didn’t work, what should I do?
    I think it doesn’t matter for me about worm that shown when i open autoCAD, the main problem is I can’t use command “move” in my CAD, when I command move, the object is coppied…what should I do?

    • Metin Şaylan Dec 20, 2012

      This worm sometimes changes commands in your lisp files. Try running LspCleaner to clean your computer. If it still doesn’t work, you may need to reinstall your autocad.

  • ame Dec 19, 2012

    it works bro… thanks a lot..

  • Abraham Jan 12, 2013

    Thank God for your life. It works!!!!!!

  • Megan Feb 1, 2013

    I cannot get AutoCAD to load at all, so I cannot use the APPLOAD command. Is there another method I can use?

  • Gabbs Feb 11, 2013

    Thank you very much!! you’re a genius! :D

  • Peter Fisher Feb 15, 2013

    hello will your script work on an lisp virus that changes the default AutoCAD 2009 menu, and affects how hatch patterns display and affects plotting also?

    • Metin Şaylan Feb 16, 2013

      Acaddoc.lsp has many side effects. If your drawings create acaddoc.lsp files in every folder you open a drawing, then acaddoc.lsp virus may be your problem. Then this script will work. Otherwise, it may be caused by another virus. Generally acad.lsp virus changes menus. Read more about it here.

  • pallavi Mar 6, 2013

  • Mpr Jun 14, 2013

    flish,
    Just open autocad and type appload .
    Then navigate to wherever you saved the script file.

  • gf Jun 18, 2013

    Thank much Metin Saylan. It’s really help me. May I re-post this posting on my blog in indonesian language? For share n help indonesian CAD user, who get problem cause acaddoc.lsp

  • caduser Feb 10, 2014

    I can’t manage to unzip acaddocfix version 1.8. I had no problem with version 1.7, I think that the worm was killed, I ran the commands in the acaddocfix_1.7.lsp file on the autocad command prompt and I don’t get acaddoc.lsp files created in each drawing folder. However, version 1.8 zip file is recognized as a vitus (not the content, the zip file). Is this normal? Is there a difference between versions 1.7 and 1.8? Thank you in advance.

    • Metin Şaylan Mar 30, 2014

      They do the same thing, I just removed the portion that added auto cleaner to acad.lsp. So that once virus is removed it no longer occupies your pc. I suggest using LispCleaner application instead of lisp files.

  • Johanes Mar 11, 2014

    You really help me a lot!!!!! It used to take minutes just to open one CAD files because of all the routines it load. But now it’s instantly open…..THANK YOU…..

  • Natroshi May 20, 2014

    Hi Metin Şaylan

    I loaded the routine, but the acaddoc.lsp archives still appears. I run your lsp cleaner and all the acaddoc.lsp archive was deleting. So what i did wrong??
