Corrupt acad.lsp

[software]

We have received a dwg file from a consultant that corrupts our installation of Arch Desktop 3.3 and the acad.lsp file. The dwg file somehow has an embedded script in it that runs when open. It adds the following lines to the acad.lsp file
(load
"acadapp")
(princ)
The acadapp.lsp is also created by this embedded script(corruption) and contains many narfarious setvars and commands and undefines many commands. It then spreads to master files if xrefed to them as well. Thus acting like a virus and corrupting many files.

Has anyone seen anything like this and know how to fix it?

open help and do a search on macros.

Look for "VBA projects embedded in drawing files
create potential macro virus risk"

Thanks! However from what I can tell there are no macros embedded in this dwg. Autocad is set to detect macros however this warning does not come up nor are there any macros listed when vbarun is run.
