此时你会发现，若系统联网，clamav会自动下载病毒库

贰，关于离线下载病毒库

main.cvd 下载链接
daily.cvd 下载链接
bytecode.cvd 下载链接

下载完成后，上传至/henan/clamav/update目录下
并执行如下命令
clamdscan --reload。它会通知clamd去重新加载病毒库。
在守护进程关闭的情况下，运行如下命令进行扫描
/henan/clamav/bin/clamscan -r /henan/pack/

clamdscan --version，查看版本信息。

叁，有网络的情况下更新病毒库：

运行如下命令更新病毒库：

systemctl stop clamav-freshclam #关闭守护进程

/usr/local/clamav/bin/freshclam #
