The 3ds Max Scene Security Tools is Autodesk's recommended way to detect and remove known 3rd party malicious scripts identified as CRP\ADSL, ALC, ALC2, PhysXPluginMfx, MSCPROP, 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.
