执行 crontab -r,但还是会生成。

ll /etc/cron.d
-rw-r--r-- 1 root root 117 Apr 11 10:18 root

这个文件随时在修改, vi 保存的时候提示 WARNING: The file has been changed since reading it!!!

现在只能把 crontab 停止,然后重启机器。

这是病毒脚本

检查下是否有 rookit 吧。还有命令都要检查一遍。最后重装系统。

这个病毒,之前论坛里已经有很多讨论了,腾讯和阿里都出了解决方案,搜一下就有答案了.....

你这个有点强势,我中的那个憨憨病毒因为没有 root 权限,直接 kill 掉连自启动都做不到

如果你不能对系统里的所有文件进行排查,那么还是建议你重装系统。

即使你今天发现了出问题的病毒文件,也不代表剩下的那些文件就没被改动过。
可能过几天其它文件又让你系统后门大开了。
