I scanned an EICAR signature, rared and zipped 3 times, via mod_clamav.
It works for me.

Please check :
- your configuration files (ArchiveMaxFileSize, ArchiveMaxRecursion, 
ArchiveMaxCompressionRatio, ArchiveBlockEncrypted, ArchiveBlockMax)
- ls -l /usr/local/lib/libclamav.*
You should have only one version of libclamav with good symbolic links 
pointing to it.
