Windows 10: Strange empty folder randomly appears on desktop

Hi folks -

I sometimes look at my main production system and notice that every so often this folder appears on my desktop:





The solution is to delete the empty folder, but I sense that since the title is in hex, it might be from the registry.
Seems encrypted.

Has anyone seen this behavior before?

TIA *Think

Undelatable, Unnamed Ghost Folders on Desktop

So, these appeared on my desktop randomly - they cannot be renamed, they appear to have no name - I can delete them via context menu, but they come back. Unlocker/Lock Hunter - they do not see them, neither does Explorer, WinRAR nor CMD.

The context menu on them is strange - it only has three options.

I checked both C:\Users\User\Desktop and C:\Users\Public\Public Desktop\ and neither of them have these folders in them. They only show on the desktop.

I would like to get rid of these permanently, any suggestions?

 

Desktop folder randomly opening

So for the past couple of days (after the latest update maybe) my Desktop folder randomly opens up. I searched online for a while and found several posts suggesting it could be the keyboard so I've switched out my keyboard and the problem still persists.
I've run Kaspersky and MalwareBytes but no threats were found. Any suggestions to resolve this? Thanks

 

Strange floating panel with symbols & numbers randomly appears

For several months, with no apparent reason or trigger, this strange floating window has appeared - its almost always in the way and sometimes is hard to get rid of. There is no way to close it, its not clickable - I seem to be only able to get it to go away by tabbing between programs. I have tried searching round to see if anyone else has this but have not found any reference to it. Hoping someone else may know what this is!

First attachment shows the object... the second one shows it hovering about over my desktop.
