Strange, I run a script called hourly by cron and here is a snippet of what I have in /var/lib/clamav on one of my servers:

drwxr-xr-x 2 amavis amavis    4096 2007-07-13 13:15 daily.inc
-rw-r--r-- 1 amavis amavis 9351789 2007-06-12 17:11 main.cvd
-rw------- 1 amavis amavis    1352 2007-07-13 13:07 mirrors.dat

As you can see, this particular server has one of each (daily.inc & main.cvd). I have no idea why this is, since my other servers have daily.inc and main.inc. The server that has main.cvd is running Fedora 7 and ClamAV 0.91.
