斑竹先生们及各位高手：最近机子中了病毒，首页被病毒修改为www.511.cc，同时只要过一段时间不操作电脑，就会自动打开几个网页，链接到www.sun12.com和www.tingcn.com以及www.uu550.com。关闭这几个网页后又会弹出几个网页。虽然这些网页可以手动关闭，但是不胜其烦。使用瑞星修复了被这个病毒屏蔽的注册表和改动的首页，但是自动打开IE的现象依旧。使用hijackthis扫描如下：

请各位帮忙看看，问题出在什么地方？谢谢！！！

开始→控制面板→性能和维护→管理工具→服务→查找File Replication Services→右击→属性→启动类型→禁止→应用→停止→确定。

重新启动电脑, 开机检测完后, 按[F8]键(可以一直按到启动菜单出来为止), 选择安全模式进入Windows

运行Hijackthis，扫描结束后在下列选项前打上勾，然后选修复“Fix Checked”：

显示隐藏文件

双击我的电脑--工具---文件夹选项--查看选项卡--单击选取"显示隐藏文件或文件夹"--清除"隐藏受保护的操作系统文件（推荐）"复选框。在提示您确定更改时，单击“是”--单击“确定”。

然后找到如下文件并删除（如果有的话）。

C:\WINDOWS\system.exe
C:\WINDOWS\System32\NtFrs32.exe

非常感谢！但是删除symtem.exe和NtFrs32.exe后，系统出现过两次无法进入的情况，然后采用“最后一次起作用的正确配制”进入。不知是否有关？

没事，现在您的问题解决了吗？
