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。 用WINDOWS的查找功能进行查找并删除：
F:\WINDOWS\Downloaded Program Files\barhelp22.0.dll
winupdate.exe
