它出什么问题了？
答案1
您正在运行缺少各种设置的 freshclam 配置文件的默认示例。
如果你运行：
sudo dpkg-reconfigure clamav-freshclam
它将在/etc/clamav/文件夹中创建一个新的 freshclam.conf 文件。
从文件夹中删除现有的 freshclam.conf 文件/usr/local/etc/。
sudo rm -f /usr/local/etc/freshclam.conf
然后创建指向新文件的链接，以便如果您再次运行它，conf 文件将保持更新。
sudo ln -s /etc/clamav/freshclam.conf /usr/local/etc/freshclam.conf
然后运行freshclam进行更新。
sudo freshclam
您可能会收到此错误：freshclam: error while loading shared libraries: libclamav.so.7: cannot open shared object file: No such file or directory，可以通过运行以下命令修复：
sudo apt-get install --reinstall libclamav6
或者对于 Ubuntu 16.04：
sudo apt-get install --reinstall libclamav7
或者，我还没有尝试过这个，但据说它适用于任何发行版：
sudo ldconfig

如果我以此为例我会说
LogVerbose
不是有效命令，后面必须跟“是”或“否”。链接中说：
# Use system logger (can work together with LogFile).
# Default: no
LogSyslog yes
# Specify the type of syslog messages - please refer to 'man syslog'
# for facility names.
# Default: LOG_LOCAL6
#LogFacility LOG_MAIL
# Enable verbose logging.
# Default: no
#LogVerbose yes
LogSysLog 也是如此。这可以解释您的通知：
