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。）

先终止下面的进程（关闭所有窗口，同时按下CTRL+ALT+DELETE，在打开的窗口中选中要终止的进程，然后按下“结束任务”或者“结束进程”，最后关闭该窗口。
C:\WINDOWS\System32\msupdater.exe

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）
