New Risk Detected - File / Entry Unavailable

Hey there -

About a month ago I upgraded to SEP 12.1.4 and I am loving the new feature to report risks as they are indentified.  Today I recieved a Risk Alert that was very vague and generic.  The Risk was a "WS.Reputation. 1 Malware" and the File / Entry was "Unavailable".

What would make it unavailable?  Is there any way to get around this in the future so we know when the alert comes in as to what file it is classifying as a risk?

Thanks!
