Disable real time scanning and restore the files and zip them up as mentioned here and forward them as mentioned in the link to Mcafee.
You will get an immediate reply. Please reply to that changing subject of the email to False +ve and name of detection. Say in the email body why you think it is a false detection and post the analysis id number here.
If no fix in 4 days post back and I will stir a tech up.
Oh reenable real time scanning as soon as you email the files. Best to send them as two separate submissions.
