我的电脑是自动联网的，昨天开始，有时没上网突然会弹出一个广告网站的小框框，今天又出现过几回，感觉网速好象慢了，这是什么东东？请大侠们指点一二，不胜感激。

请您先下载HijackThis1.99.1（它是免费的）：

http://www.spywareinfo.com/~merijn/files/hijackthis.zip
将它解压到一个非临时性的文件夹（比如C:\Program Files\HijackThis\HijackThis.exe）。然后双击HijackThis.exe图标，选择Do a system scan and save a logfile，将产生的文本文件中的日志帖上来。如果一个帖子贴不下，可以将剩余的部分另开一帖。

重新启动到安全模式（进入安全模式的方法:重新启动电脑, 开机自动检测完后, 按[F8]键(可以一直按到启动菜单出来为止), 选择安全模式(Safe Mode)进入Windows。）

请关闭所有IE界面，重新使用HijackThis扫描一次，选中下面建议修复的项目，让HijackThis修复，修复前请允许HijackThis保留备份。（如果楼主知道是安全的可以不必勾选）

然后打开我的电脑→再点工具→打开文件夹选项→查看→把隐藏受保护的系统文件（推荐）和隐藏已知文件类型的扩展名的勾去掉→再显示所有文件→找到以下文件并删除：(如果有的话)
C:\WINNT\SYSTEM32\stdup.dll
删除文件夹C:\WINNT\WORLD2
删除文件夹C:\PROGRA~1\MMSASS~1
