Check http://www.clamav.net/support/mirror-problemforpossible reasons.freshclam升级报错原因这个问题可能是由于网络连接问题导致的。Can’t query current.cvd.clamav.net的错误提示表明ClamAV无法连接到病毒数据库服务器。解决方式1 先ping以下病毒库pingdatabase.clamav.net可以ping通ping database.clamav.net 得到一个ip 如104.16.219.5 再然后改/etc/hosts这个文件。加入一行[rootclamav clamav]# vim /etc/hosts104.16.219.5 database.clamav.net2 重启网络service network restart或者/etc/init.d/network restart3 再次升级ClamAV病毒库freshclam升级成功。
