建议卸载360搜！

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:\WINDOWS\System32\nvrsed32.dll
C:\PROGRA~1\INTERN~1\HMAPI
C:\WINDOWS\MSMNSGER.EXE
删除文件夹C:\PROGRA~1\360so

请楼主自己确定，如果不认识也请修复并删除相关文件。
