stevedrew Posted January 22, 2016 Posted January 22, 2016 (edited) I am running AutoCAD Civil 3D Land Desktop Companion 2009 on Windows 7 platform. 64 bits I believe a CAD file has been infected by a virus. I located an article on Autodesk:https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-detect-and-remove-the-Acad-vlx-virus-s.html that identifies the Acad.vlx virus, which I am wondering if this is the culprit. I believe I incurred the culprit when I downloaded an AutoLISP extractable file e.g. MTEXTMask and loaded it via APPLOAD command. During preload I scanned the file but did not detect any recognizable problems. After I launched the file and work for a brief amount of time, things spontaneously began do crazy things during operational commands, panning and zoom. For example: during a line command and picking point for a line there is no response on screen. Also during pan and zoom it appears entities are disappearing and if I zoom extents everything appears to disappear. I can close it without saving and the drawing will open successfully with the last save, but continues to be a problem. I followed the Autodesk article directions adding the code to the LSP files and searched for the code to be added or removed from the target files indicated with the the instructions. I also ran a whole computer virus scan with AVG Zen that didn't detect a virus. The problem still remains opening the same file that is infected. I do not want to open other files fearing they will become infected also. Has anyone else had this problem and could it be once the file is infected is it corrupted forever or it is recoverable to a workable state? Any help or suggections is very much appreciated...

ReMark Posted January 22, 2016 Posted January 22, 2016 Is this the article you are referring to? https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-detect-and-remove-the-Acad-vlx-virus-s.html Once the virus has been removed your drawing file should be fine.

ReMark Posted January 22, 2016 Posted January 22, 2016 (edited) Then it is possible that the original source of the virus has not been eliminated. I believe it is spread via an acaddoc.lsp file that gets replicated numerous times. Miss one instance and you reinfect your system all over again every time a drawing is opened. Maybe the Killworm.lsp program by Ahankhah in post #12 of this thread might help solve the problem. http://www.cadtutor.net/forum/showthread.php?58117-acad-viruse/page2&highlight=acad.vlx Edited January 22, 2016 by ReMark Quote
Cad64 Posted January 22, 2016 Posted January 22, 2016 What you're experiencing doesn't sound like the acad virus. It sounds more like a graphics display problem. Do you have hardware acceleration enabled? Are your video card drivers up to date? And as for the drawing disappearing after zoom extents, it could just be that you have a single object sitting way out in space somewhere.
