NAV 11.1 Virus Detected in Scan but not Quarantined

I'm having some trouble doing anything about a virus that NAV just told me it found after a hard drive scan.  It says 4 problems were detected in the activity log, and it says the main window that the virus was called 7bb99554-61214fe3.  It wasn't quarantined, and I do not know what to do about it.  Thanks.
