What is preferred method to get new software on 4.10 stable?

[Andy Firman]

Let's take Clamav for example.  My freshclam logs say this:
WARNING: Your ClamAV installation is OUTDATED - please update immediately !

So, I have clamav-0.75.1 installed from ports.

What would be the proper way to get clamav .80 installed?

pkg_delete clamav-0.75.1 and then install .80 from source?

Or is there some mechanism to get .80 in from the ports?


Thanks,
Andy
