I have just received an email with an unknown virus. I happily passed through my scanners. I have checked it's still unknown to all of 4 anti-viruses I have an access to.
I have already reported it to ClamAV and to Kaspersky but I when I tried to report it to other systems I quickly gave up. Some of them require registering, some require reporting as an encrypted email attachment. It's difficult to put a sample into over a dozen of antiviral systems.
Is there a single service for reporting virus samples?
