Broken ClamAV Update – Update your systems now

Dear Customers,

There was a bad virus definitions file pushed out by ClamAV early this morning that has broken all installations of ClamAV.

We have been busy fixing systems while a new release of virus definitions by ClamAV is worked on.

If you are experiencing slow email delivery or high CPU on your BarricadeMX, BarricadeMX PLUS or DefenderMX systems, please follow the following instructions for your specific version.

Execute the commands:

echo “Vbs.Downloader.Generic-6431223-0” >> /var/clamav/local.ign

DefenderMX or DefenderMX Enterprise

Login to your system as root
