clamav configuration to block zip virus?

[I Love Jesus]

Clamav cannot block the EICAR test .zip file attached to email.
Therefore Viruses in zip files can get throught. See testvirus.org. Test 11,18 and 20-25 all failed. How can I configure Clamav to block this virus?

I just had Chirpy's Mailscanner frontend installed and all of those tests were blocked.. highly recommended!
