If you have installed by use of an older version of this script you can now run it again for upgrade (also if you are currently using the version from Be aware that older versions of ClamAV (0.65) had DoS vulnerabilities and that the ClamAV database has changed dramatically from version 0.80 with new mirror functionality so an upgrade might be a very good idea.



[root@e-smith]# wget -N

[root@e-smith]# sh


You can now try to send a test "virus" email by attaching one of the signatures you can find at This enables you to see whether the system detects this signature file and whether your admin account ( receives the virus notification email.

Usually this happens if your system is trying to update virus database while a new is being uploaded on the database server by the Clam team. The error message should not happen the next time the antivirus panel updates.
Where are the Quarantined and Problems emails located?

Quarantined emails will be quarantined in /var/spool/amavis-ng/quarantine and Problems emails in
