Hello @Redskins1791
fwiw ~ by my experience here…$AV_NLL folder is created with an initial quarantine event…and $AV_NLL folder remains…until you clean install Norton.
meaning you’ve cleared Security History → Quarantine?
meaning you’ve deleted quarantined files?
Was there a quarantine event on C & D?
Have you tried temporarily disable Norton - Product Tamper Protection and then try deleting $AV_NLL folder?
Please post progress
Edit: fwiw ~ as test:
temporarily disabled Norton - Product Tamper Protection and then deleted $AV_NLL folder.
