我的系统是vista，在系统目录system32下面有个文件jnsfhf.dll，系统启动时报错，加载jnsfhf.dll错误，文件正在使用，使用瑞星杀毒20.60提示，该文件为trojan.DL.win32.undef.vt病毒，但是无法删除，在20.61.50版本后，提示该文件为同样病毒，删除成功，但是文件仍然在文件夹中，启动是仍然报同样错误，手动删除文件，提示正在使用，用安全模式删除文件，同样提示。使用控制台删除，也是同样提示。本想提交文件作为病毒样本，但是不能备份，不能压缩，都是提示文件正在使用，查找注册表和进程服务，也找不到jnsfhf.dll。网站上查找jnsfhf.dll，也找不到相关的内容。
目前使用了我所知道的所有办法，问题仍然解决不了。高手们，救命啊！！

楼主试试试用瑞星光盘引导杀毒，或者安装卡卡上网助手后，重启动计算机，再使用瑞星升级到最新来杀毒。

瑞星杀毒软件的所有方法我都使用过，没用

那就根据此帖操作：
http://bbs.ikaka.com/showtopic-8410701.aspx

瑞星的听诊器查不出任何问题，空的，也没有生成什么文件

听诊器所在文件夹会生成一个“瑞星听诊信息.htm”文件的。将此文件提交。

没有这个文件  瑞星听诊信息.htm
听诊运行以后，进度条走完以后没有任何结果

不知道UNLOCK支不支持VISTA.

楼主安装UNLOCK然后使用UNLOCK删除试试.

几经努力，瑞星听诊器总算有个结果文件
但是好像没有什么异常

未知家族病毒分析
扫描结果:
无可疑文件

好像不全啊，楼主重新扫一遍，之后将听诊信息直接提交上来。
