[clamav-users] Detected duplicate databases

[Al Varnell]

The first time freshclam pulls down a daily.cdiff file, your daily.cvd file will be decompressed to daily.cld and the .cdiff file added to it. From that point on you should only have the daily.cld file. One exception is that if for some reason freshclam is unable to find needed .cdiff files on a mirror, it will download a new .cvd file which will start the process again.

It is possible to reconfigure freshclam to download .cvd files by disabling incremental updates, but that would be very inefficient use of bandwidth and mirror server time, so unless you have a overriding need for that, I don't recommend it.
