You will get an immediate reply post the analysis id number here and reply to the email changing the subject to false +ve and name of detection. Say why you feel it is ok.
If no fix in 4 days post back and I will stir up someone to fix it if it is a false +ve detection.
If you are using the 13.6 version of security center you can exclude the file from scans but if it actually is a bad file this will cause you problems thus I suggest go the submission path..
This exclusion in Virus and Spyware Protection / Real Time Scanning
