你说的这两项是卡卡扫描的吧，在此之前我的机子有些问题，用HijackThis扫了个日志，已发贴并通过“我无邪”指导，采取了措施。所以以上两个扫描是处理后的情况。我操作的依据是“我无邪”高手的指导。

我无邪的指导：
开始→运行→输入services.msc，打开“服务”→查找Gray_Pigeon_Server2.03，Network Management Center Task →双击→启动类型→禁止→停止→应用→确定。禁止Gray_Pigeon_Server2.03，Network Management Center Task这2个服务 （每一个逗号隔开的就是一个病毒的服务，请逐一禁用）
重启后
修复

双击我的电脑--工具---文件夹选项--查看--单击选取"显示隐藏文件或文件夹"清除"隐藏受保护的操作系统文件（推荐）"复选框。在提示您确定更改时，单击“是”
删除

我刚用两个扫描同时进行了扫描，日志还是不一致。

那就谢谢轩辕小聪和一楼的老师了！
