怎么判断病毒所属呢？
1、通过勒索信息文件、加密后文件后缀等勒索特征判断勒索病毒家族。
2、选择对应家族（如有版本也应选择对应版本）的解密工具；
3、解密前需对重要的数据进行备份（即使处于被加密状态），以防止解密失败造成损失；
4、解密前需确保系统中的勒索病毒已被清除，否则可能遭到重复加密；
5、部分解密工具可能需要特定的解密环境（如在原始受感染的主机上进行解密、需要同时提供加密文件和原文件等），具体请参考工具中的说明。
6、解密工具可能只对某些家族的特定版本生效。

5、 防范方法
1：关闭服务进程（杜绝445端口）
2：注册表关闭勒索病毒服务
3：开启防火墙，防微杜渐过滤危险端口
4：组策略安全设置、ip安全策略
