Installing ClamAVConnector with cPanel

Apparently new stock installations of cPanel and ClamAVConnector from “Manage Plugins” fail with the default preferences.

How can you tell if you have a failed installation? By checking if freshclam exists on the server:

root@test [~]# freshclam
-bash: freshclam: command not found

If this is the case, the culprit is probably cPanel’s memory settings which you can tweak via WHM under “Tweak Settings”.

The maximum memory a cPanel process can use before it is killed off  (in megabytes). Values less than 256 megabytes can not be specified. A  value of "0" will disable the memory limits.

Set this to 512 MB, then go to “Manage Plugins” and uninstall “ClamAVConnector”. Once it’s done re-install and “freshclam” should work and there you go! Working ClamAV installation.

root@test [~]# freshclam

Of course, if things still don’t work, make sure “RBL: zen.spamhaus.org and rbl.spamcop.net” is checked in “Exim Configuration Editor”.
