clamd Not loading PUA signatures. ERROR: Malformed database

检查freebsd7.x的邮件系统,发现/var/log/maillog提示:

MailScanner[36664]: ERROR: Malformed database

检查clamd的log记录,提示错误信息“

Not loading PUA signatures. ERROR: Malformed database”

如下:

tail -f /var/log/clamav/clamd.log
Reading databases from /var/db/clamav
Not loading PUA signatures.
ERROR: Malformed database

clamd daemon 0.92.1 (OS: freebsd7.0, ARCH: i386, CPU: i386)

发现clamav的版本还是老的版本0.92.1,此老版本已不支持现在新的database数据库格式了,所以报错,clamd进程也启动不了!解决办法就是升级clamav为最新的版本,目前是clamav-0.97.3,关于怎么升级,此处不再做介绍,请参阅本blog相关文章!
