2. 防止 Windows 运行您在这个设置中指定的程序
   REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer" /v DisallowRun /t REG_DWORD /d "00000001" /f
   REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\DisallowRun" /v login.scr /t REG_SZ /d login.scr /f

   REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\DisallowRun" /v sethc.exe /t REG_SZ /d sethc.exe /f
   REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\DisallowRun" /v WinPcap.exe /t REG_SZ /d WinPcap.exe /f

   REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\DisallowRun" /v sql.exe /t REG_SZ /d sql.exe /f
   REG ADD "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\DisallowRun" /v su.exe /t REG_SZ /d su.exe /f
    
3. 关闭445端口
   reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters" /v SMBDeviceEnabled /t REG_DWORD /d "00000000" /f
   
4. 关闭135端口
   reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole" /v EnableDCOM /t REG_SZ /d "N" /f
   reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc" /v "DCOM PRotocols" /t REG_MULTI_SZ /d "" /f
    
5. 禁止dump file的产生和删除现有MEMORY.DMP文件(dump文件在系统崩溃和蓝屏的时候是一份很有用的查找问题的资料。然而，它也能够给黑客提供一些敏感信息比如一些应用程序的密码等。)
   reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl" /v CrashDumpEnabled /t REG_DWORD  /d 00000000 /f
   attrib %SystemRoot%\MEMORY.DMP -s -r -h
   del %SystemRoot%\MEMORY.DMP /s /q /f
   
   
6. 去除HappyTime(欢乐时光)威胁
   reg delete HKCR\CLSID\{06290BD5-48AA-11D2-8432-006008C3FBFC} /f
   reg delete HKCR\Scriptlet.TypeLib /f
   
7. 禁用通过重启重命名方式加载启动项
   重启重命名的执行优先级比传统的自启动（一般指HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\Run）要高, 启动完成后又将自己删除或改名回去. 这种方式自启动极为隐蔽,现有的安全工具都无法检测的出来。病毒通过重启重命名方式加载，位于注册表HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\ BackuPRestore\KeysNotToRestore下的Pending Rename Operations字串。
   reg delete "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager" /v PendingFileRenameOperations /f
   
8. 关闭事件跟踪程序
   REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Reliability" /v ShutdownReasonOn /t REG_DWORD /d "00000000" /f
