Pre-ClamAV Upgrade Questions

Hello group..

I folowed the HTF tutorial: The Perfect Server - Ubuntu 9.04 [ISPConfig 3]

I wanted to verify if under the above installation that ClamAV was installed from 'Packages' OR 'Source'?

Just wanted to check prior to proceeding with the Upgrade instructions at: http://wiki.clamav.net/Main/UpgradeInstructions

It is time to upgrade ClamAV to the newest version I found this morning when I logged into ISPConfig3 Monitor.

Thank you in advance for your help and information.

Best Regards
