Good.

This looks like a labelling issue. Can you post the output of:
# ls -lZ /etc/freshclam.conf
# restorecon -v /etc/freshclam.conf
Which packages are you using for clamav? I see nothing in the Extras
version that might result in this.

All the remaining audit messages are not SELinux-related.
Can you let me know if freshclam works OK in enforcing mode after doing
the "restorecon" above please (also look for any more AVC messages).
