Hi Matthew,

as a temporary solution you can run the following command:

echo "0:0:ffffffff:DOS exe(or not):CL_TYPE_BINARY_DATA:CL_TYPE_MSEXE" > 
/usr/local/share/clamav/local.ftm

(you may need to change the db path). This will change the way how some specific
files are being handled (in your case we just don't want to handle them as
CL_TYPE_BINARY_DATA). Also, we now have a bug entry for this problem:

Thanks,
