    Hi!

    Does anyone know if there is any past history of NOD32 to interact with AutoCAD dwg files?
    My CAD specialist starts to point on the one thing he doesn't control - the AntiVirus Program :D

    Kind Regards

    Welcome Molas

    Although not using NOD32 currently, I had previously a license.
    I cannot recall any negative issues w/ NOD32 and the AutoCAD release I was using at the time.
    You can try Eset's online scanner to see how ACAD files react:

    I have never had any problems with dwg/dxf files.
    They are easily excluded anyway.
    I have never heard of dwg/dxf being infected, bit of a waste of time for a virus writer - very little propagation.

    What is actually happening? Files won't open, files won't save?
    Are the .dwg files located on the same workstation or on the network?
    Are they extremely large (i.e. could they take some time to scan on open/change?)
    Does the problem persist if you change real-time protection to scan only the listed extensions?

    There's at least one AutoCAD related threat with launch linked to dwg files - Just search for 'dwg virus'

    Cheers :)

    I've been in the CAD business for 25 years, and yes I do know what you are referring to.

    The vast majority of viruses written for CAD systems are script virii, in the Autocad case - AutoLisp. You have to open a dwg for the script to be activated, the virus is not in the dwg but in the AutoLisp 'executable'

    I open/save dwg & dxf day in, day out and could run without any AV due to a simple fact.
    My CAD program 'opens' a dwg dile by converting it to it's own format.
    If a virus was inserted into a dwg it would be a corrupt file and not open.

    It's rather like creating a virus for the jpg format. If you target Photoshop it will not hit Mediachance.


    Answer - don't use AutoCad:argh:

    Hello Molas,

    I can see not much interest in Autocad here.
    I am mechanical design engineer and I am using Acad and Inventor almost every day. Right now I have NOD32 v3 latest build and "zero" problems so far with dwg, dxf, idw, dwf, ipt, iam files. I had a problem once with Inventor 2008 when the ekrn.exe went "cucu" 99%. I called Autodesk and Eset and the solution was to exclude Autodesk from scanning. I've done that temporary and after a while I reset NOD32 back to default settings. Everything is fine, no conflicts so far.
    If you have problems go into setup > HTTP > web browsers, and place a red cross next to any autodesk related entries in the list. You'll have a smooth and still safe PC.

    I'm using AutoCAD Electrical 2008 with NOD32 3.0.672.0 without problems. There was an issue a few months back where NOD was flagging a DLL file belonging to AutoCAD but this was cleared with a subsequent update.

    No issues have appeared with any DWG, DWF files etc.
