The ZA folder in the Quarantine does not want to remove itself from the Hard Drive, means the Quarantine folder cannot be deleted.

Thanks

I have had 4 users where once the Zeroaccess folder is moved to Quarantine (for FRST) even by FRST itself, in Normal and Recovery Modes FRST still fails to delete its quarantine.

I have a 75 year old user as the last one left.

One user, I had manually step by step shift the Zeroaccess folder back inside the Install folder so the FRST\quarantine folder would then delete as soon as the Zeroaccess folder is moved out.

The Zeroaccess folder is able to be moved around in Windows, but won't delete at times, for the parent folder it is inside to, Including _OTL hahahaha
