The way is report this as a false +ve and it should be fixed in a few days
When they reply ie foul\nd a virus reply changing the subjest to False +ve detection and name of the detection. Leave the body of the email as is and add why you think the file is ok and a link to where to get it.
Post the analysis ID here and if no fix in 4 days post back and I will chase it up.
OK I sent it in, analysis ID 7532129
Thanks if no fix in 4 days post back and I will ping a lab tech.
This file was classified as clean and should no longer cause a detection.
