So what I know:
Centos7
EPEL Repo is the one delivering clamav

The packages available are
[root@ip-172-31-13-51 ~]# yum list available| grep clam
clamav.x86_64 0.99.2-1.el7 epel

clamav-unofficial-sigs.noarch 3.7.2-1.el7 epel
clamav-update.x86_64 0.99.2-1.el7 epel

only clamav is mentioned in that technique.

manually doing yum -y install clamav works flawless, this is a bug.
I'm 90% sure it's related to the number of dashes in packages if they share a common name part.
