Good.

Reading kernel sysctl (not sure what for)

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.

Trying to read /proc/sys/kernel/ngroups_max

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).
