ClamAV not updating to 0.94-3vm.el5

virtualmin reports: clamav A GPL virus scanner New version 0.94-3vm.el5 Virtualmin
But install fails with "no package found". I have tried to turn off all yum plugins and removing all repos but virtualmin to no avail.

My virtualmin repo (cleaned up keys) looks like this:

[virtualmin]
name=Red Hat Enterprise $releasever - $basearch - Virtualmin
baseurl=http://######:XXXXXXXXXX@software.virtualmin.com/rhel/5.2/$basearch/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-virtualmin
gpgcheck=1

[virtualmin-universal]
name=Virtualmin Distribution Neutral
baseurl=http://######:XXXXXXXXXX@software.virtualmin.com/universal/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-virtualmin
gpgcheck=1

Any help would be appreciated. I am getting daily mails from the system that the update failed. When I do the update manually this is what happens:
