我安装了 clamav 和 clamtk。clamtk GUI 可见但似乎什么都不做。如果我在 CLI 上执行：clamav，我会得到 clamav：未找到命令。如果你执行：sudo clamav clamav-freshclam，我也会得到：clamav：未找到命令。如果我执行：freshclam，我会得到：错误：无法打开/解析配置文件 /usr/local/etc/freshclam.conf 重新安装 clamav 和 clamtk（sudo apt-get install clamav clamtk）没有帮助。
谁能帮忙？

软件包的名称并不总是可执行文件的名称。要查看软件包安装的文件列表，请运行dpkg -L package-name。在本例中，可执行文件为：
$ dpkg -L clamav | grep /bin/
/usr/bin/clambc
/usr/bin/clamscan
/usr/bin/clamsubmit
/usr/bin/sigtool
您正在寻找的那个最有可能是clamscan扫描文件或目录以查找病毒。例如：
$ clamscan /tmp/clam/
/tmp/clam/foo: OK
/tmp/clam/bar: OK
