A Microsoft file hosting and synchronization service.
Hi Chet,
Welcome to this forum.
First of all, OneDrive is not a kind of malware.
I noticed that you want to delete the file within OneDrive. I uninstalled OneDrive and I noticed that one file still on there and I can't delete it. It is FileSyncShell64.dll.
FileSyncShell64.dll is part of Microsoft OneDrive and developed by Microsoft Corporation. It may cause some unknown error if we delete that file.
Regards,
Neo
