The latest version of smeserver-clamav-unofficial-sigs is available in the SME repository, click on the version number(s) for more information.



ClamAV comes with a default database that is regularly and automatically updated. Next to the default database there are additional 'unofficial' databases that can be added to ClamAV. This contrib smeserver-clamav-unofficial-sigs adds various and well known databases to the default installation of SME Server, providing better chance of protection to viruses, malware, ransomeware and phishing attempts.

Note for Securiteinfo sigs

read this before installing :


The smeserver-clamav-unofficial-sigs contrib is available from the fws and the epel repositories. These repo's should be enabled first. Please see fws and epel on how to enable these repositories. After both repositories have been enabled you can install smeserver-unofficial-sigs by the following command:

yum install smeserver-clamav-unofficial-sigs --enablerepo=fws,epel

Since there are much more signatures, ClamAV needs more memory to operate correctly. To set the required memory enter the following command:

config setprop clamd MemLimit 1500000000

followed by

signal-event clamav-update

To invoke the download of the unofficial signature databases the following script has to be run once (it's in the SME Server $PATH):

That's it, ClamAV now has a lot more signatures to work with, and will automatically update all signature databases.
