我用2K系统，在“c:\winnt\system32\”这个目录中，有个lpfbi.dll文件，大家看看是不是病毒，用瑞星杀不了，用killbox也删除不了，说正在使用，在安全模式也删除不了，大家有什么建议，请指教？

用killbox的delete on reboot功能也不能删除，在安全模式下也不能，瑞星的文件粉碎功能也不行，这可能是比较厉害的病毒。

我现在发个日志上来，给大家看看：

这个文件我在纯DOS下已经删除了，但是还有一个问题没有得到解决，那就是每当开机进入系统时，会有一个RUNDLL错误提示，说不能加载C:\winnt\system32\lpfbi.dll文件。在注册表中已经给删除所有与lpfbi.dll的键值了，请大家帮忙看看有关rundll加载文件的具体方法，谢谢大家了。。
