then the outstanding question is how to figure out why certain packages are not being updated.
Well, first action: did you actually check with the repo that there is a newer package? Just because a package isn't updated doesn't mean it's not working. Especially in the case of clamav I think you haven't done the obvious. Please read before continuing: http://wiki.centos.org/AdditionalResources http://wiki.centos.org/PackageManagement/Yum
