unknown command error for simple commands

[asilis]

Hello everyone,
i'm ITing an engineering office of about 20 pc's that run various versions of autocad (from 2006 to 2010).

Last week it started occuring that basic commands like 'line','move','extend/trim' or 'quit' and 'plot', are not recognized. (oddly enough , 'circle' and 'polyline' ARE recognized)
searching the net i came across this discussion:

http://forums.autodesk.com/t5/AutoCA...ds/m-p/2716073

but i'm not sure what is means by unloading express tools. and adding some .lsp files; how do you unload express tools? do you restart autocad? and what .lsp routines should one load afterwards? any? some specific?

This week the problem has spread like a virus to other pc's too. So it feels like something is tampering with Autocad.
additionally i see an acad.lsp file being created in every directory that a dwg file has been edited/created this past week.

Has anyone seen this? is there a solution?

I'm afraid reinstalling the program in 20 computers will not solve the issue if the acad.lsp is still there. BUT is it enough to delete the acad.lsp from each folder? will that solve the issue?

Thank you for your help

Ignore that thread - it sounds like the "acaddoc.lsp virus" (google it).
Here is one of several threads that discuss it.

Its not the acaddoc.lsp unfortunately.
Got this virus a few months ago.
Fixed it with a nice lsp routine I found.

This time around its not acaddoc though...

AutoCAD loads the first acad.lsp or acaddoc.lsp it finds within the drawing directory or the Support File Search Paths. You need to track down where this file is initially being created and remove it. Search your drives for the two names above.

well that did it.
some acad.lsp files that i deleted in the users directories have solved the problem

thanks!

I'm glad you found it - now you need to figure out how it got into your system.
