DFIR CTF: Malware Memory - Question 9

For 

What is the name of the JSON file that exists inside the NetDefender directory?

when running the command:

vol.py -f malwarememory.vmem --profile=Win7SP1x86_23418 filescan | grep -i "NetDefender" <-- Aided by Gemini for faster querying based on the possible arguments

.in terms of using filescan to grep for NetDefender directory files, no JSON files were observed. I am wondering about what I am doing wrong.
