刚刚在最近安装的 14.04 lubuntu 上运行 chkrootkit,它想出了:
Searching for suspicious files and dirs, it may take a while... The following suspicious files and directories were found:

如您所见,存在一些异常情况;那些可疑文件和目录是什么?在 /sbin/init? chkutmp?我在我的另一台机器上没有得到任何类似的结果......所以我也尝试了 rkhunter,我会发布整个日志文件,但它的字符太多,并且帖子限制为 30000

rkhunter 似乎并不表示suckit,那么这是来自chkrootkit 的误报吗?还是rkhunter的假阴性?那些其他警告怎么样,谁能给我任何关于它们的含义的见解?我在谷歌上搜索了一些异常结果,但找不到任何东西......这通常是一个坏兆头。
那么,我是否有 Rootkit,如果有,我该如何移除它并修复造成的任何损坏?
