    Exclamation ClamAV 0.94 EOL on ZCS 5.0.16 prior

    For those using ZCS 5.0.16 and prior, come 15 April 2010 anti-virus definitions will no longer update AND your ClamAV instance will stop working entirely.

    Preventative methods:
    -Upgrade ZCS.
    -Update just the ClamAV component.
    -Set zimbraVirusDefinitionsUpdateFrequency to 0 well in advance of that day to avoid receiving the remote disable code.

    If reading this already past the 15th options include:
    -Turn off ClamAV from your admin console > server > services 'as/av' tab > uncheck av. Via CLI it's zmprov ms `zmhostname` -zimbraServiceEnabled antivirus. (The minus sign is important, or you'll have nothing but av running.) Then zmamavisdctl reload or zmcontrol stop/start. (This may leave you more vulnerable of course, so schedule a maintenance window as soon as you can.)
    -Update just the ClamAV component.

    -Upgrade ZCS.

    If your intent on keeping your old version, you may have trouble with your Amavisd-ClamAV. We include ClamAV 0.95 as of ZCS 5.0.18+, there are of course other security reasons to upgrade such as the third-party CVE-2009-3555, in addition to other bugs and multiple RFE's. ZCS 6.0.6 & 5.0.23 Shipped!
