你进安全模式把C盘的垃圾文件清一下，然后看看有没有恶意进程，我想可能是垃圾，如果你是ghostXP安装的系统。

病毒隐藏了自己。

不知道你这个是什么？？

<\SystemRoot\\SystemRoot\System32\drivers\nbnjsap.sys><N/A>

请问大家现在有什么办法杀毒？我刚刚在安全模式下也没杀到毒，也整理了磁盘，没发现容量大。谢谢！

不可能吧.一个系统就是2.5G左右了啊..C:\WINDOWS+C:\Program Files+C:\Documents and Settings 应该不止2.5个G吧..

你看看C盘根目录下的每个文件夹属性，看看每个文件夹的大小。

看来只有采取最简单办法重装电脑了.
