I get this when I start my Zimbra server

Code:

The thing is that the ClamAV databases exist here:
/opt/zimbra/data/clamav/db/daily.cvd.init
/opt/zimbra/data/clamav/db/main.cvd.init

NOT

/opt/zimbra/clamav/db/daily.cvd.init
/opt/zimbra/clamav/db/main.cvd.init


Does anybody know why it's looking in the wrong directory for the .init files?

/opt/zimbra/clamav/db/ does exist, but there is nothing in it.
