This issue is caused by insufficient permissions in registry. The registry keys involved can be seen in a ProcMon log:

  1. HKEY_CURRENT_USER\SOFTWARE\Symantec\Symantec Endpoint Protection
  2. KEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\AV\Custom Tasks


    An example seen in ProcMon:

ACCESS DENIED on RegCreateKey for SymCorpUI.exe on registry path- HKEY_CURRENT_USER\SOFTWARE\Symantec\Symantec Endpoint Protection\AV\Custom Tasks\Temporary Quick Scan Options {FFEE7373-7E6F-4E06-9883-44C4FBF4BB47}

Note: "Temporary Quick Scan Options" will appear only when running a scan.





WARNING: The following steps require editing of the system registry. Prior to editing the registry, make a back up the registry.
Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify only the registry keys that are specified.

Change the permission the listed keys to the following:

  1. Administrator - Full Control
  2. SYSTEM - Full Control
  3. Users - Full Control
  4. Restricted - Read (may not present)

Note: Make sure All the permissions above apply to "This key and subkeys" and the permissions are inherited to child registry keys by checking the option - "Replace all child objects permissions with inheritable permissions from this object"
