[CentOS] clamav

Hi all,

I tried:

/usr/bin/freshclam -l /var/log/clamav/clam-update.log

and I got some warnings telling me that my ClamAV installation is OUTDATED 
- please update immediately!...

then I tried:

yum update clamav, but no clamav package was found.

Does anybody know how to update clamav using yum or any other updater???

Thanks,
JC
