打开注册表编辑器。

1、展开：HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
删除：<BIE><RUNDLL32.EXE C:\PROGRA~1\baidu\iexp\BDSrHook.dll,Rundll32>


2、展开：HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon

将<Userinit><userinit.exe,C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\aceci.exe,C:\WINDOWS\system32\netsend.exe> 改为<Userinit><userinit.exe>

3、重启系统。显示隐藏文件。
4、找到并删除：
C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\aceci.exe,C:\WINDOWS\system32\netsend.exe。
C:\PROGRA~1\baidu\iexp\BDSrHook.dll
5、用SREng修复文件关联。

好的，应独孤豪侠要求，再用hijackthis扫一份，注：这一份是我已经修复了c:\ progra~1\baidu\iexp\BDSrHook.DLL这个之后的扫描日志：

据我这两天的了解，我知道这个有问题，F2 - REG:system.ini: UserInit=userinit.exe,C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\aceci.exe,C:\WINDOWS\system32\netsend.exe
但是实际上aceci.exe和netsend.exe都是我上周已经用killbox删除过了的，现在它们又出来了
