我已经使用 ClamAV 很长一段时间没有任何问题，但是就在本周，每当我尝试更新病毒定义数据库时，我开始收到以下错误：

[root@staging milindr]# freshclam

但是，当我尝试更新它时，我得到以下响应：

[root@staging milindr]# yum -y install clamav clamav-update

Nothing to do

不确定为什么会出现这个问题以及我可以做些什么来解决它，因为我尝试按照 https://www.clamav.net/documents/upgrading-clamav上提供的步骤更新我的 clamAV 版本，但这不是很好也有帮助。

我对 Linux 环境有点陌生，感觉在某个地方错过了重要的一步。提前致谢。

0.102.4是过时的旧版本。实际版本是0.103.5或更新。

以下是您无法更新的一些原因ClamAV：

  1. Amazon 远程存储库已过时且不再维护（您应该更新您的 Linux 操作系统以便能够迁移到新的存储库）。如果您使用当前的 EC2 实例几年而没有更新，这种情况最有可能
  2. 本地存储库信息已过时。sudo yum update安装前尝试运行ClamAV更新本地信息

如果sudo yum update没有帮助，请尝试下载最新版本clamav-0.104.2.linux.x86_64.rpm并手动安装（不要忘记先删除旧版本）。
