高手帮忙看看这个文件是什么文件？系统？黑客？木马？呵呵。。也许是流氓软件？文件位于c:\windows\system32文件夹下隐藏的，在注册表里是HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved，名称是{66CD5F60-A044-11D0-A9BF-00A024E3867F}数据是‘weifeng’。我在google上查了一下没有相关介绍，只好求助这里的高手！

上面是这个文件的下载地址，是我上传的。
再有就是文件夹选项/查看/隐藏文件和文件夹 两个选项的效果反了，选择显示所有结果隐藏的文件都隐藏了，选择隐藏所有结果隐藏的文件都显示出来了。不知道是什么原因，如何修复？
上面两个问题，希望各位兄弟姐妹帮我解决以下，我在这里谢谢各位了！！！
