My email server is using Postfix as the MTA and Clamav as the anti-virus software running on Centos 5.4. Today I check the version of Clamav installed on it and it is already out-dated so I need to upgrade to the latest stable version. The installed version of clamav is ClamAV 0.94 whereas the latest stable version is ClamAV 0.95.2.
Upgrading clamav installed on Centos is easy. You just first backup the current configuration of clamav (/etc/clamd.conf and /etc/freshclam.conf).
Basically if you install clamav for the first time, you need to edit and modify the config file of clamav (clamd.conf and freshclam.conf) to meet your need. You do not wanna lose these files because it takes time to edit them.
Here are the upgrade processes:
Now restore the backup files to /etc folder and then restart the clamav service.
Check the clamav version:
Do not forget to update clam antivirus database using freshclam.
Since I live in Indonesia, I use db.id.clamav.net as DatabaseMirror in the freshclam.conf file but got errors when running the freshclam update like below:
We have to try another mirror sites. Run ‘freshclam –list-mirrors’ to see available mirror sites.
There are three available mirrors. The first one was failed (db.id.clamav.net), the second one is located at Ireland and the third one is located at Sweden.
I choose the third one, the Sweden. The domain country code of Sweden is ‘se’ so the db clamav domain must be ‘db.se.clamav.net’. Set the DatabaseMirror in freshclam.conf to be db.se.clamav.net and then run freshclam update again.
Now your clamav has been upgraded and the clam antivirus database also has been updated successfully. Restart the clamd service again.
