Well, I just successfully upgraded my servers' clamav installation from clamav-0.60 to clamav-es-0.75.1. Here are the directions:
Upgrading your Clam AV (SME v5.X ONLY):
1. Determine your Clam version
rpm -q clamav
rpm -q clamav-es
rpm -q clamav-es-libs
If you have 'clamav-es' and 'clamav-es-libs', skip ahead to step 6
If you have 'clamav', continue at step 2.
2. Download the current 'clamav-es' and 'clamav-es-libs' rpms to your workstation.
http://www.pagefault.org/code/e-smith/antivirus/6.0.1/i386/3. Make a directory on your server, and move these rpms to the server. Either using WinSCP, ftp, or your favorite method.
4. Change to that directory on the console (or PuTTY window).
5. Remove the 'clamav' rpm from the system
rpm -e clamav
6. Install/Upgrade the new clamav rpms
rpm -Uvh clamav-es*.i386.rpm
7. Run 'freshclam' to update the virus signatures
[root@Server clam]# freshclam

[root@Server clam]#
8. ClamAv is installed/upgraded correctly. Now, we need to verify the configuration and make sure that it is scanning mail correctly.
- For SME v5.x, follow this howto:
http://www.pagefault.org/howto/amavis_clam.shtml (Start with the section titled "Clam Daemon Configuration")
I really didn't have to change much. But, I ran each command just for the heck of it. And, make sure you double-check your Amavis-ng config, and your Mailfront Configuration as specified in the howto.
Hope this helps.
