CVD (ClamAV Virus Database) is a digitally signed tarball file that
|
||
|
|
contains one or more databases. You can find some useful information in the
|
||
|
|
ASCII header of the file. It's a 512 bytes long string with the following
|
||
|
|
colon separated fields:
|
||
|
|
<PRE>
|
||
|
|
ClamAV-VDB:build time:version:number of signatures:functionality
|
||
|
|
level required:MD5 checksum:digital signature:builder name
|
||
|
|
</PRE>
|
||
|
|
and can be easily parsed by scripts or with <code>sigtool --info</code>.
|
||
|
|
There are two CVD databases in ClamAV: <I>main.cvd</I> and <I>daily.cvd</I>
|
||
|
|
for daily updates. You can use <I>sigtool</I> to unpack a CVD file
|
||
|
|
(<code>--unpack</code>) and to list virus names (<code>--list-sigs</code>).
