3ds Max Scene Security Tools

3ds Max Scene Security Tools

Digitally signed app



The 3ds Max Scene Security Tools is Autodesk's recommended way to detect and remove known 3rd party malicious scripts identified as CRP\ADSLALCALC2PhysXPluginMfxMSCPROP, and their variants. The malicious scripts can corrupt the Autodesk® 3ds Max® environment, cause data loss and instability, as well as spread to other systems through sharing of 3ds Max scene files.

Autodesk recommends that all customers running supported versions of 3ds Max, including 3ds Max educational licenses, 3ds Max Indie and 3ds Max Trial versions, download and install the 3ds Max Scene Security Tools application to help detect and resolve issues caused by 3rd party malicious scripts.

What's new in version 2.1.7:

  • Added support for 3ds Max 2025.

  • Removed support for 3ds Max 2019.

What's new in version 2.1.5:

  • Added support for 3ds Max 2024.

  • Removed support for 3ds Max 2018.

What's new in version 2.1.4:

What's new in version 2.1.3:

  • Fixed issue where a scripted runtime exception is thrown when starting 3ds Max 2019 Update 2 and 3 after installing version 2.1.2.

What's new in version 2.1.2:

  • Added methods to the Security Tools Function Publishing System interface for querying the number of problems found and the number of problems fixed.

What's new in version 2.1.1:

What's new in version 2.1.0:

  • Implemented support for detecting and removing the MSCPROP malicious script.

What's new in version 2.0.1:

  • Fixed an issue where the "Notify me about updates" option would notify users of new updates when in fact their installation of the Scene Security Tools was up-to-date.

What’s new in version 2.0.0:

  • The tool has been renamed to “3ds Max Scene Security Tools.”
  • The “Notify me about updates” option informs users of new versions of this tool published on the Autodesk App Store. This option is enabled by default.
  • The tool has been re-written in C++ to increase its flexibility and robustness in protecting users against 3rd party malicious scripts found in scene and script files.


  • Detects and removes the malicious scripts listed above from 3ds Max startup scripts and scene files regardless of how they are loaded.
  • Helps prevent 3ds Max from saving scenes corrupted with the malicious scripts listed above.
  • Asks for user confirmation before cleaning startup scripts and scene files.
  • Works in quiet and non-interactive usage scenarios of 3ds Max, such as command line rendering and batch scripting.
  • Logs actions to the system log (Max.log) and to the MAXScript listener.
  • Allows the user to continue using 3ds Max even if they choose not to clean startup scripts or scene data.

Important note:

The 3ds Max Scene Security Tools is designed to help repair affected 3ds Max scene files and 3ds Max’s user environment. It is not intended as a general endpoint protection tool and should not be considered as such. Autodesk recommends that all users run a reputable antivirus or anti-malware program on their computers and keep both the program and its virus definitions updated regularly.

    I'm glad I kept the 2.1.3 installer or this would be a one star review and I would have to use a paid alternative, which is a piece of crap

  • Issue
    Jonike Lu | July 11, 2021 Verified Download (What's this?)

    A dialog box will pop up every time you open the scene, which is troublesome. Can you add an automatic clear function in quiet mode?

    Attila Szabo | July 12, 2021

    Hello Jonike, I was unable to reproduce the issue you reported using 3ds Max 2021 or 2022 with the latest version of the Scene Security Tools, namely 2.0.1. I ran 3dsmax.exe -silent and opened a few files that contain the known malwares. When 3ds Max is in silent mode, Scene Security Tools cleans the scene and environment automatically, and logs these actions to the Maxscript Listener and Max.log For example: ALC2 Security Tool 1.3 - ALC2 corruption found in file: <path_to_infected_scenefile> ALC2 Security Tool 1.3 - Automatic cleanup of ALC2 in scene performed since in quiet mode. What version of 3ds Max and Scene Security Tools are using?

    Debe instalarse en alguna carpeta en concreto?

    Attila Szabo | December 01, 2020

    Simplemente siga las instrucciones del programa de instalación. La herramienta debería instalarse de forma predeterminada en C: \ ProgramData \ Autodesk \ ApplicationPlugins \ 3dsMaxSecurityTools. Háganos saber si este no es su caso..

  • Why you get malicious code?
    Ülkü Roger Schlesinger | November 09, 2020 Verified Download (What's this?)

    I never download any 3dsmax software from malicious webservers. Only from Autodesk.

    I never has any problems with 2017.

    Julio Bahamonde | November 11, 2020

    As far as i know the malware can be spread by 3d models and other assets you load into MAX. I had the .ALC problem a couple of months ago, Before this tool i used Prunescene.mzp wich is some sort of antivirus that runs inside MAX, detected and cleaned the infected scenes when opening and gives you the possibility to scan folders too, worked great.

  • Use Autodesk Security Tools Only!
    | September 05, 2020 Verified Download (What's this?)

    I have a bad experience using Prune Scene. This program contains a virus generator that is detected by the anti-virus proactive defense systems for operating systems (HIPS). Be careful.
    It somehow penetrates the system folders, the system registry and creates its own Trojan generator. It is very difficult to remove it from the operating system. It prevents 3ds Max from starting and infects scenes.

    Use Autodesk Security Tools Only!

    Mastaman 3dground | December 23, 2020

    This is a lie. Show evidence!

    RuivoCreative LDA | July 19, 2021

    There is a code defect in 3ds Max 2015 that prevents the package from being loaded. This defect was fixed in 3ds Max 2015 SP1. The problem was that 2015 did not properly handle SeriesMax values in PackageContents.xml that are greater than 2015.

  • new virus ALC3 ?
    Sergey Dugin | March 31, 2020 Verified Download (What's this?)

    The same as ALC BETACLEANER, but with some differences.

    The most dangerous thing is that this virus can download updates for itself and can be modified!

    This virus take next issues:

    • Crash 3Ds Max when open
    • Empty helper nodes
    • Unable to use the Undo function
    • Displays various MaxScript errors
    • Change render settings (V-Ray): VFB size, materials, GI settings etc.
    • Tiny save your render from VFB and send to remote e-mail
    • Gather system information and send to remote e-mail: IP, MAC, HDD info, Memory, CPU, 3Ds Max version etc.
    • Send gathered data from fake e-mail sss777_2000@126.com (nfkxovtedspjgedv) to rrr888_3000@126.com
    • Download from remote address and update itself from http://www.maxscript.cc/update/upscript.mse

    The script saves itself into hidden files in the:

    C:/Users/Your User Name/AppData/Local/Autodesk/3dsMax/Release Number - 64bit/Lang/scripts/startup
