Basically the question here is does Norton/Symantec delete the "LOW" folder? It seems to be the culprit because I can create this folder manually or use the tool provided by Microsoft in this article:

ANd within a few minutes the folder disappears. If I recreate the folder and disable Norton/Symantec, the folder will stay there for an extended period. As soon as I turn Norton/Symantec back on the folder eventually disappears.
