Hi mon_raralio,
It is normal, Create different Folders for updates. These Check these folders,
"C:\Program Files\Symantec\Symantec Endpoint Protection Manager\Inetpub\content\{C60DC234-65F9-4674-94AE-62158EFCA433}"
64-bit definitions: "C:\Program Files\Symantec\Symantec Endpoint Protection Manager\Inetpub\content\{1CD85198-26C6-4bac-8C72-5D34B025DE35}"
For some time the folders are created and Disappears but it still keep doing that for several minutes.
You have check for the Space for the Drive where the updates are installed.
It might be an issue with the low space in the drive.
