Malware submission address

Sorry for a repetitive question, seems I have been using the wrong search terms latley and coming up with no results?

Tried to submit the package that I thought might contain malware virus, spyware, trojan, but most probably a rootkit. OR I could be paranoide :THNK I will forward the returned email to the correct address

I received this note from the Postmaster.

Thanks for the correct address or addresses (not sure why I think there are two at Comodo?)
