Actually this 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.
Update: I created a small program to clear this virus from your lisp files. Download LspCleaner here.
Follow these steps to get rid of this worm:
- Download the routine:
acaddocfix_1.8.zip (1.1 KiB, 12,322 hits)
- Load the lisp file using APPLOAD command
- The lisp file will run automatically and it will clean all the existences of the worm in your support folders.
- 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 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 ^^
