As far I understand, rspamd treats viruses detection as a spam.
I would like to see in the rspamd dashboard, in the graphic status and in the throughput, how many mails have been blocked because they contain viruses and how many have been blocked because they are spam.
Well not sure that you could separate easily spam and virus. History is stored in a redis database
to connect : redis-cli -s /var/run/redis-rspamd/rspamd
Mail are rejected with this tag CLAMAV_VIRUS(1)[Eicar-Test-Signature] in history, but after that I do not know much.
I suppose that you have to interrogate the redis database
