For my particular install on CentOS 5.1 x86_64 I received a similar error.
when running this command:
yum --enablerepo=rpmforge install clamav clamav-db clamav-milter clamd -y
...in lieu of this rpm install:
rpm -Uvh rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
...which is in lieu of this guide:
http://www.howtoforge.com/virtual-hosting-with-virtualmin-on-centos5.1-p2I receive a similar error:
clamav-filesystem conflicts with clamav...
Of course, you can't just:
yum remove clamav-filesystem
...as that would require you remove virtualmin-base.
To "solve" this problem:
rpm -e --nodeps clamav-filesystem
...and then rerun the above
Then re-run the above:
yum --enablerepo=rpmforge install clamav clamav-db clamav-milter clamd -y
Of course then you have the new problem of VM trying to update clamav to it's version...I think this only happens in x86_64 settings.
