1. 第一步查找被木马写入的文件(看修改时间)。  

2. 对于不能删除的文件。

a) stop httpd 以后再删除。 

b) 脚本监视 删除 

Try the watch command.

Usage: watch [-dhntv] [--differences[=cumulative]] [--help] [--interval=<n>] 
             [--no-title] [--version] <command>`

So that:

watch -n1  command

will run the command every second, forever.

On Mac OS X, you can get watch from Mac Ports, or you can get it via Homebrew:

brew install watch
