scan returned empty file list； check that path exists and contains files in scope of configuration

Ubuntu上安装和使用恶意软件检测工具 LMD 及杀毒引擎 ClamAV；

安装参考：https://yq.aliyun.com/articles/87014

本人在/usr/local/maldetect/conf.maldet 配置文件中 设置了cpulimit 限制cpu的使用

1、maldetect 安装后执行扫描无效果

maldet --scan-all /tmp

root@sxs-dev16:~# maldet --scan-all /tmp

maldet(28807): {scan} building file list for /tmp, this might take awhile...
maldet(28807): {scan} setting nice scheduler priorities for all operations: cpunice 19 , ionice 6
maldet(28807): {scan} scan returned empty file list; check that path exists and contains files in scope of configuration.

处理方式：去掉cpulimit限制；

sed -i -e 's#scan_cpulimit=".*\?"#scan_cpulimit="0"#' /usr/local/maldetect/conf.maldet

参考：cpulimit bug in LMD v1.6.4    https://ask.csdn.net/questions/4988055

2、clamscan进行扫描报错：/usr/local/clamav/bin/clamscan /root

root@sxs-dev02:/srv/wkk# clamscan -v
LibClamAV Error: cl_load(): No such file or directory: /usr/local/clamav/share/clamav
ERROR: Can't get file status

 需要有可用的病毒库文件，同时用户和组的权限也需要设定。

# 更新病毒库
