PGP NetShare Overlay icon is not displaying on secured folders
This appears to be a problem with PGP NetShare interpreting the size of the icons.
Adjust the display size of the icons to "Medium" and the PGP NetShare overlay icon should be displayed properly. Press F5 to refresh the view.
Unregister and reregister the PGPfsshl.dll (the lock icon overlay dll).
In the command line, "regsvr32 /u PGPfsshl.dll" will unregister the dll and "regsvr32 PGPfsshl.dll" will register it.
In another scenario, upgrading the OS from Windows 7 to Windows 10 resolved the issue for Symantec Encryption Desktop 10.4.1.
