> I have no servers that are ever allowed to access the internet. Is there a way to download the pkg file not using pkgutil?
wget and many others will do it, the package file is just on a URL.
Choose a file, eg:
Download to anywhere, eg, your home machine.
Transfer to your server by any means, eg, USB stick, CD, floppy, local network, etc.

I’m running ClamAV on a lot of clients on my local network. Can I serve the cvd files from a local server so that each client doesn’t have to download them from your servers?
Sure, you can find more details on our Mirror page.
If you want to take advantage of incremental updates, install a proxy server and then configure your freshclam clients to use it (watch for the HTTPProxyServer parameter in man freshclam.conf).
The second possible solution is to:
Configure a local webserver on one of your machines (say machine1.mylan)
Let freshclam download the *.cvd files from http://database.clamav.net to the webserver’s DocumentRoot.
Finally, change freshclam.conf on your clients so that it includes:
First the database will be downloaded to the local webserver and then the other clients on the network will update their copy of the database from it.
Important: For this to work, you have to add ScriptedUpdates off on all of your machines!
I can’t wait for you to update the database! I need to use the new signature NOW!
No problem, save your own signatures in a text file with the appropriate extension. Put it in the same dir where the .cvd files are located. ClamAV will load it after the official .cvd files. You need not to sign the .db file .
Can I download the virusdb manually?
Yes, the virusdb can be downloaded from the Latest releases section on our home page.
save your own signatures in a text file with the appropriate extension
CVD (ClamAV Virus Database) is a digitally signed container that includes signature
databases in various text formats.
The easiest way to create signatures for ClamAV is to use filehash checksums,
however this method can be only used against static malware.
MD5 hash-based signatures
To create a MD5 signature for test.exe use the --md5 option of sigtool:
zolw@localhost:/tmp/test$ sigtool --md5 test.exe > test.hdb
zolw@localhost:/tmp/test$ cat test.hdb
That’s it! The signature is ready for use:
zolw@localhost:/tmp/test$ clamscan -d test.hdb test.exe
test.exe: test.exe FOUND
You can change the name (by default sigtool uses the name of the file) and place
it inside a *.hdb file. A single database file can include any number of signatures.
To get them automatically loaded each time clamscan/clamd starts just copy the
database file(s) into the local virus database directory (eg. /usr/local/share/clamav).
