is this an ALC-virus in max

[Anonymous]

These have been created since using the 2018 version. It is not possible to delete it, and it is not possible to unhide it. I do not have any trouble in my work, but I keep getting nervous. For reference, I am using the 2017 version at the same time.

I explained using a translator. I would appreciate it if you would understand this point.

Was it always like this or have you installed a plugin, used a callback or some other method that would make these appear? 

When max starts, it opens a default file, is it possible that this has those inside? If so, can you replace the max file from another source and see if it happens when you start max again?

Could it be part of a plugin  thats been removed?

Could be a max bug, but check out some of the above to see if anything shows up (or doesn`t)

Maybe a legacy item from 2017? The icon seems to suggest a helper object or something like that. 

In the listener type/run this and see if any data relative to those objects show up.

for o in objects do
(
	format("Name: " + o.name + "\n")
	format("Class: " + (classOf(o) as string) + "\n")
	format("SuperClass: " + (superClassOf(o) as string) + "\n")
	format("Class ID: " + (o.classID as string)  + "\n")
)

One of my users just reported the same issue, and after opening his test-file, i got it too. So now even after restarting max, I get the nodes in my scenes (even when resetting).

The nodes can be deleted if you rename them first, but that doesn't stop max from creating them again when you make a new scene

I've attached a file if anyone else feels like looking into this... but don't open it unless you are prepared to deal with this issue

I'll try to look further into it tomorrow, and keep you posted if I find a solution!

Sorry i forgot to get back on this. It turns out it is caused by the ALC-virus in max (or ALC 'issue' as autodesk calls it)

Here is the official explanation:

https://knowledge.autodesk.com/support/3ds-max/troubleshooting/caas/sfdcarticles/sfdcarticles/Scene-...

I've talked to Raiden Xavier from the Autodesk Support Team, and he gave me the attached files to help resolve the issue (Thanks). The zip-files contain two max-scripts and a text-file instructing you to place them in 3ds max' startup folder. 

The maxscripts removes files generated by the virus, cleans nodes in scenes you open, and removes callbacks belonging to the virus. 

Please note that the tool only looks for particular viruses and removes them, but doesn't close the underlying security issue, so always be aware when opening .max files from untrusted sources. (and yes, i do see the irony in warning about .max-files and supplying you with a .zip)

Just encountered this, thanks for the solution.

I have to open files from people I don't know, it's part of my job. Autodesk needs to come up with a real solution to this in a patch so it cannot happen. We can't be expected to know where every single max file came from or what other models that user might have imported in the past.

This is Virus. There is a some file you can download from internet.

Hello Kate, 

Thank you for your reply, this is a topic that we are taking very seriously. Do you have an idea on how you would like this ideal solution to work? Say you open a file from someone you don't know, what do you wish would happen next? What type of information would you like to see and which actions would you like to be able to take?

Thanks a lot for your feedback 🙂

For anyone dealing with corruption causing scripts embedded in 3ds Max scenes, I highly recommend to install the 3ds Max Security Tools from the Autodesk App Store. It supports 3ds Max 2015 SP1 to 3ds Max 2021.

Here are the links to the Autodeks Knowledge Base articles describing the corruption causing scripts we are aware of:

• Support article on CRP and ADSL MAXScripts
• Support article on ALC MAXScripts
• Support article on ALC2 MAXScripts
• Support article on PhysXPluginMfx MAXScripts

If you see anything suspicious in a 3ds Max scene, or your 3ds Max is acting wierd, please drop us a line here on the forum or contact our support specialists.
