勒索病毒全球肆虐，除了朝鲜无国幸免，以下是收罗的两则处理方法：

一、使用腾讯的免疫工具，对比腾讯、金山、360，个人认为腾讯这次的免疫工具最好用。下载网址：http://guanjia.qq.com/wannacry/

二、使用代码，一键设置防火墙禁止规则，禁用137，138，139，445端口

附：在cmd状态下批量执行以下命令可关闭危险端口：
net stop SCardSvr
net stop SCPolicySvc
sc config SCardSvr start= disabled
sc config SCPolicySvc start= disabled
net start MpsSvc
sc config MpsSvc start= auto
netsh advfirewall set allprofiles state on
netsh advfirewall firewall add rule name="deny udp 137" dir=in protocol=udp localport=137 action=block
netsh advfirewall firewall add rule name="deny tcp 137" dir=in protocol=tcp localport=137 action=block
netsh advfirewall firewall add rule name="deny udp 138" dir=in protocol=udp localport=138 action=block
netsh advfirewall firewall add rule name="deny tcp 138" dir=in protocol=tcp localport=138 action=block
netsh advfirewall firewall add rule name="deny udp 139" dir=in protocol=udp localport=139 action=block
netsh advfirewall firewall add rule name="deny tcp 139" dir=in protocol=tcp localport=139 action=block
netsh advfirewall firewall add rule name="deny udp 445" dir=in protocol=udp localport=445 action=block
