Though I did forget to mention:
After you get this working with 4.5.7 (or .8 if you wish) with no more differed mails, "Can't connect to INET socket 127.0.0.1:3310" errors, etc you may wish to update clamav manually.
See here a list of fixes:
Bug 20568 - Clamav update to version 0.91.2
As always, be sure to have a full backup of your /opt/zimbra/ directory first!
We always recommend to get on the current version anyway; because if you have a problem that builds from this, it's hard to troubleshoot if it's a bug or if it's just you

(Someone had trouble on a v3 version the other day & that's a little old when v5.0 is about to roll out...& even v4.0 -not to be confused with v4.5- is approaching EOL)
Just the DB:
Quote:
su - zimbra
mkdir /tmp/clamdb
mv /opt/zimbra/clamav/db/* /tmp/clamdb
zmprov ms `zmhostname` +zimbraServiceEnabled antivirus
/opt/zimbra/clamav/bin/freshclam --config-file=/opt/zimbra/conf/freshclam.conf
zmamavisctl stop
zmamavisctl start
