数据恢复代理是 EFS 架构中最高权限的存在，它保证在特定情况下加密数据依然可被恢复。简单来说，DRA 是一个授权用户（通常是管理员），它持有特殊的恢复证书和私钥，为 EFS 体系提供了一把“万能钥匙”。这一功能在以下场景中尤为重要：

If you suspect a virus, you should immediately run a full system scan with a reputable antivirus program. Never try to manually delete the file from the System32 folder unless you are absolutely certain it is a fake.
