The Windows Indexing service is locking the files and they cannot be deleted after an update.
What To Do
You need to exclude certain folders Sophos AutoUpdate uses so the Windows Indexing does not block updates or lock files and prevent their deletion. For more information see article 59494.
In older versions of Sophos Endpoint Security and Control the sophos_autoupdate1.dir folder was located in C:\Windows\Temp\. In Sophos AutoUupdate 18.104.22.1683 and later the folder is located in the 'Cache' folder.
