【回复“石人”的帖子】
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）
F2 - REG:system.ini: UserInit=userinit.exe
所有01项

O3 - IE工具栏增项: (no name) - {F60C7D81-8471-4D40-AAFE-56D318F34C2D} - (no file)

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：

C:\WINDOWS\System32\Usign.dll
