Today, a backport of libclamunrar6 from (non-free) unstable (version 0.95.2-1) was added to lenny-backports. This package provides unrar support for ClamAV (both clamscan and clamd) and it works with the version of ClamAV from Debian Volatile.
This makes the custom version of clamav and related packages, that has been in lenny-custom for a while, redundant, so they have been removed from the repository.
libclamunrar6 is available for amd64 and i386 architectures.
