Thanks, I think it is very likely it was that false positive, still, I’m greatly disappointed due to not being able to check the details of that alert… All I can check is the log of the start scan done after the alert, and it didn’t find anything. I’d really want to know what file supposedly was deleted. I still hope there is a log hidden somewhere.

P.S: sfloppy.sys is where it is supposed to be, and a manual scan doesn’t report it as virus.
