rkhunter扫描结果

Question

我是新来的Ubuntu和我寻求一些帮助。我已经用rkhunter扫描了我的Ubuntu，我有一些值得关注的结果：

我想知道这些是否是假阳性或真正的威胁，关于如何解决它们。非常感谢!

Answer 1

RKHunter以它的假阳性而闻名。ClamAV更好！

那三个隐藏的目录并不危险！我从2010年起就收到了这些通知。

Java是由Oracle创建的，也是由OpenJDK为数字证书创建的。

/dev/. udevd由udevd守护进程创建。

/dev/.initramfs的/run/initramfs符号链接是系统启动过程中安装初始ram文件系统的位置。

您可以无问题地删除它们，它们将在必要时由系统重新创建。
