开始--控制面版--管理工具--服务--找到System Managements Instrumenta 属性--改为已禁用

显示隐藏文件，找到以下删除：
winnt.exe（使用开始--搜索查找）
C:\WINDOWS\System32\INTasks.exe
C:\WINDOWS\System32\lsas.exe

另，您该为电脑的系统打补丁了……

谢谢  大哥  不过大哥说的  C:\WINDOWS\System32\INTasks.exe
C:\WINDOWS\System32\lsas.exe    搜索不到啊  ````  晕 死了   
另外  我要打什么补丁啊?  请  大哥  再帮小弟一次  谢谢```

修复后，再扫个报告粘上来瞅瞅
