ClamAV DB Update leads to **UNCHECKED** in all messages

A recent update to ClamAV's DB causes clam to not start up, leading to emails being marked as '**UNCHECKED**'

This affects ClamAV version 0.97.8, and therefore the Zimbra versions affected are 8.0.6 and below, including 7.x.

  • ZCS 8.0.7+, 8.6 and 8.7 are not affected.

Manually regenerating the DB leads to the following error:

[zimbra@zcs806 ~]$ /opt/zimbra/clamav/bin/freshclam --config-file=/opt/zimbra/conf/freshclam.conf

The only fix for now is upgrade to at least Zimbra Collaboration 8.0.9, but we encourage you to upgrade to Zimbra Collaboration 8.6 and the latest Patch.

Our Technical Support Engineers might have found a workaround by disable the antivirus:

zmprov ms `zmhostname` -zimbraServiceEnabled antivirus
zmcontrol restart

But this workaround will let your Zimbra Collaboration Platform without an Antivirus, and we don't recommend it.
