[求助] 求助，服务器被入侵，请问如何解决

lee-1

如题，搬瓦工服务器，安装了WDCP3.09，今天收到邮件提示服务器检测到恶意软件被挂起

这台机器只是自己搭建用来学习Linux，没什么重要数据，重装系统也无所谓，但担心再装上wdcp还会出现类似问题

请各位大牛帮忙看看该如何解决？如果必须重装，之后应该做什么防范措施？

非常感谢。

附：后台信息如下

Reason:         Hacked/rooted server

More details:         We have detected hacking activity on this server

Additional information:
---------------------------------------------------------------------------------------------------------
KiwiVM has detected the following process on this server:
[getty] /usr/bin/bsd-port/getty

This process is a malware binary installed on the server with the sole purpose to perform abuse (DoS attacks, spamming, etc).
Seems like this server has been compromised and therefore it has been suspended to prevent further damage.
