[求助] 求助，服務器被入侵，請問如何解決

lee-1

如題，搬瓦工服務器，安裝了WDCP3.09，今天收到郵件提示服務器檢測到惡意軟件被掛起

這臺機器只是自己搭建用來學習Linux，沒什么重要數(shù)據(jù)，重裝系統(tǒng)也無所謂，但擔心再裝上wdcp還會出現(xiàn)類似問題

請各位大牛幫忙看看該如何解決？如果必須重裝，之后應該做什么防范措施？

非常感謝。

附：后臺信息如下

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.
