Did you submit it with McAfee Labs? If you have a ticket number we can check its status.
Otherwise please provide me the MD5 value for that specific file detectes and I can try to find additional information. You can add some additional information about it so it can be processed as a False Positive.
In case above information was useful or answered your question, please select "Accept as Solution" in my reply, or give a Kudo. Thanks! Nino
