[clamav-users] Eicar test string now returning Win.Trojan.Trojan-605

[Al Varnell]

I’m still looking, but so far I can’t find any Win.Trojan.Trojan signatures in the ClamAV Official database or listed in clamav-virusdb e-mail list.  

Nor can I confirm your results using my own EICAR.

Are you using any Unofficial signatures from a different source?
