Issues with Installing ClamAV on Red Hat Enterprise Linux

I'm trying to install ClamAV on my Red Hat Enterprise Linux system. I've installed EPEL for my version of RHEL, plus I enabled the optional and extras repositories for RHEL. I've done a yum install for: clamav, clamav-db, and clamav-update. I'm having issues running freshclam, plus I'm seeing a couple of errors on clamscan. What do I need to do to best resolve those?

Additionally, is there a way I can setup clamav for background scanning?

I've attached a screenshot below with my errors.

Thanks!
