Mass mailing list to report virus and malware samples to many Antivirus (AV) vendors at once;
(attach a .zip and/or .7z archive with password 'infected' and mention that pass in email + the undetected threat/virus/malware name.)R

Reporting new, undetected or zeroday malware/viruses to all vendors and their security analysts/virus labs at once, will enable you to help protect many Internet users, independent of their choice of Anti-virus software.
