大家知不知道呢？如果是的话，得怎么处理它呢？最新版的瑞星查杀不到啊。。

硬盘里又没找到这个文件。。

以上是在网上找的资料,我的e文也不好,帮不上多少,不过你很可能挂上洋马子了 呵呵,扫个日志上来吧.如果要找文件的话看你是什么系统,如上所说的话,95 98 me 它就在windows\system下,如果是2000的话在winnt\system32下,xp就在windows\system32下,因为隐藏和系统的属性,你不是很容易找到它.
你先查看系统进程里有没有它,有的话结束它.然后打开记事本,复制下边两行的内容:
attrib -h -s -r *:\windows\system32\nawadll32.exe
ren *:\windows\system32\nawadll32.exe nawadll32.bak
其中的*代表系统盘路径.你自己改一下,保存为扩展名为bat或cmd的文件,一定要自己找得到啊.双击,nawadll32.exe就改名为nawadll32.bak了.然后你再去找这个文件就能看到了.具体等上了日志再说.
