I would say it is highly unlikely that a VT scan would find anything wrong as it isn’t doing the same anti-rootkit scan as you can see from the VT results even avast doesn’t detect it on a conventional scan.
The file should be uploaded (or details about the detection) to avast as is suggested you allow it to be sent. I think this happens automatically during update checks if you have enabled the Community participation, see image.
It isn’t my email, I’m just an avast user like yourself ;D
However, that is the correct email address, ideally the file should be zipped in a password protected archive and attached to the email with the password in the email and false positive in the email subject.
