It sounds like that executeable file was running during the scan (probably included at startup). Running processes cannot be deleted. I don't know what the defender program did, but it may have deleted the file upon exit fdrom windows. But the file may still being called for in startup the registry, and then of course, it is no longer there. First, do a search (including system & hidden files) for catsrv09.exe. If it is not found, that is a good thing. Look in MSconfig startup files and see if it is listed there..if so, uncheck it. Then go to regedit (make sure you bck it up first) and search for that filename. Delete that entry.
If you don't know how to edit the system registry, do not attempt it without more detailed instructions.
