系统症状为启动的时候速度变慢，开机就有个iexplore进程为system创建。开始占用20m左右内存，一会降到2m左右。而且adsl未拨号前就有数百个封包发出。目的不明。
但在安全模式下搜遍硬盘也没有类似*_hook的程序
曾经某天norton报有一个Trojan.Dropper被隔离。后来就出现了这个奇怪的进程

日志如下，请高手帮忙看看，谢谢！！！

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。）

开始→控制面板→性能和维护→管理工具→服务→查找Windows Professional→右击→属性→启动类型→禁止→应用→停止→确定。

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:\WINDOWS\System32\Ado32.dll
C:\WINDOWS\System32\AlxTB1.dll
C:\WINDOWS\System32\SoMP3.dll
C:\WINDOWS\system.exe
C:\WINDOWS\system.dll
C:\WINDOWS\system_hook.dll
C:\WINDOWS\systemkey.dll

又只鸽子？？

谢谢各位高手帮忙。
system.exe和system.dll文件是找到并且删除了。但找不到system_hook.dll和systemkey.dll,删除后系统现在看起来正常了。没有异常进程。启动速度也快了。
不知道是不是一个新的变种

【回复“大脑袋雪人”的帖子】
找不到可能是HijackThis在修复的同时删除了该文件。
