I noticed today that Zimbra isn't working, and that the reason seems to have something to do with the virus scanner.

I did a zmclamdctl status, and the result was /opt/zimbra/log/clamd.pid: No such file or directory...

I can't imagine what would cause this, but I performed: locate clamd.pid, and that didn't bring up any results, so this is a bit worrisome...any ideas on how to fix this?
