Hi I had the same problem yesterday but unfortunately panicked and deleted the file before jotting down what it is. Performed a boot scan and everything seems fine. Ran a rootkit scan with an external system which was fine. I just wanna reassure myself but there doesn’t seem to be a log on avast about the event yesterday? the file filefloppy.sys is back where it is too. Is there any way to confirm that the deleted file was in fact filefloppy?
