NOTES:
This worm arrives on the system as an AutoLISP script bundled with a drawing file (.DWG). Once the drawing file is opened, AutoCAD then loads and executes this malware.
Upon execution, it loads a certain AutoLISP script named, acadapq.lsp. If the folder where the file base.dcl does not contain acaddoc.lsp, it copies itself to the folder where the file base.dcl is, as acaddoc.lsp.
If the folder where the current drawing file exists does not contain acaddoc.lsp, it copies itself to the folder where the current drawing file is, as acaddoc.lsp.
