When Maya starts, it automatically runs a script called userSetup.mel (or .py ) to load your custom tools and configurations. Because this script runs every time you open the software, it is a prime target for malware, such as the "vaccine" or "PhysXPlugin" viruses that can infect your scenes and spread to other users. The is a security measure that:

: Explains the underlying architecture of how plugins and scripts interface with the software at the Autodesk Images portal .

: Users typically see a security pop-up when Maya closes or starts if it detects an unauthorized change to these setup files.

You pass that. Good. Now comes the .

: The next time Sarah launched Maya, the software recalculated the checksum of the current userSetup file and compared it to the stored, "clean" value.
