Partial fix for language pack problem

The Civil 3D group within Autodesk has moved impressively quickly in providing a partial solution to the language pack problem I described earlier. What has been provided so far is a set of patches for Civil 3D 2009, 2010 and 2011 that allow Civil 3D users to remove the spurious language pack flag by opening and re-saving the affected drawings. I have not yet tested this, but I am informed that it works. What’s left to do? Obviously, not all recipients of these drawings are going to have Civil 3D. In fact, prior to isolating Civil 3D as one definite …

Civil 3D 2011 ANZ comes complete with “virus”

If you install Civil 3D 2011 using the ANZ (Australia/New Zealand) profile, when you start it up for the first time, you will see a large warning indicating that the drawing requires an Asian language pack to be installed. It also warns that this is a symptom of the acad.vlx virus: Now I know that in this case it’s not an actual virus causing the problem, but rather the ANZ template drawing being “infected” with this Language Pack requirement. I have had to deal with quite a few incoming drawings in this state, and that’s painful enough without Autodesk also …

AutoCAD virus protection update

As I mentioned in my last post, I had some reservations about the code provided by Autodesk to deal with suspect acad.vlx and logo.gif files. Based on a suggestion from Jimmy Bergmark, I have written my own, safer version which you can download here: clean_virus_safe.lsp. The comments at the top of the clean_virus_safe.lsp file explain what to do with it, but I will reproduce some of the relevant points here. Purpose: Checks for existence of acad.vlx and logo.gif files, which are associated with virus AL/Logo-A, also known as ACAD/Unexplode, ACAD/Agent.A or ACM_UNEXPLODE.B. Written as a safer alternative to Autodesk’s code …

Another AutoCAD malware warning

Shaan Hurley has posted some useful information about another AutoCAD-based virus that is doing the rounds, and I strongly suggest you read it. However, I have some reservations about the solution that is posted there and in the Autodesk knowledgebase. The LISP code suggested will delete any files called acad.vlx or logo.gif that are located in the current user’s current AutoCAD search path. There are a couple of problems with that. The search path will change depending on the user, the profile, the startup folder and the drawing folder. That means you can’t just use the code once and expect …

AutoCAD malware warning

There is a piece of malware out there written as an ObjectARX application, i.e. it will only affect AutoCAD users. It’s a China-based adware client, which Andrew Brandt at the Webroot threat blog has named Trojan-Pigrig. For full details, see here. Also, see here for AutoCAD-specific advice from the AutoCAD support team at the Without a Net blog.
