ClamAV service not running.

I'm finding that all of the messages in liquidfiles are not being virus scanned and are just showing this under messages:

File1.pdf (is being scanned for viruses, please check back in a little while. 0 in queue)

I've tried to force update the AV:

[rootuser@liquidfiles ~]$ sudo ft av_update
[sudo] password for rootuser:
Do you want to remove the existing AV signatures (only do this if there's a problem)? y

But the clamAV service will not start.

What can I do?
