About
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

Installation
You can just install clamav-unofficial-sigs from smecontribs/epel and it should work OR use the full contrib:
yum install smeserver-clamav-unofficial-sigs --enablerepo=smecontribs
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 1610612736
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):
clamav-unofficial-sigs.sh
That's it, ClamAV now has a lot more signatures to work with, and will automatically update all signature databases.
Configuration
/etc/clamav-unofficial-sigs/os.conf is templated and will override the default in /etc/clamav-unofficial-sigs/master.conf.
Avoid to update manually the content of /etc/clamav-unofficial-sigs/master.conf as it could be updated by the script itself.
You can manually override what you want by editing /etc/clamav-unofficial-sigs/user.conf.

Known issue
If you want to disable a single database from one provider, there are two way to do it : either this is known database that have a high risk of false positive then you can set the rating for this provider lower :
For securite info spam_marketing.ndb is set as HIGH in master.conf. If you set default_dbs_rating to MEDIUM/LOW or securiteinfo_dbs_rating to MEDIUM/LOW this db will be excluded.
Let's say that the db bothering you is provided by securite info which also provides other db that are important for you, you could edit the master.conf manually and either comment out the line with the db name or increase the level of it. However, the file could be updated by the main script and you might lost the changes.
