我的电脑一直上网，并安装了瑞星正版的杀毒软件和防火墙，并定期升级（大概10天左右）
可是从周三（9.13）开始，开机一会（状态栏显示上网连接的时候）便会提示：“svchost.exe应用程序错误 0x7c9305f8指令引用的0x00000010内存。该内存不能为read”，然后选择“确定”停止该程序，“取消”调试该程序。点“取消”开始VC调试（晕～自己当然不会调试了～）。出现该提示后，出去“混音器”不能使用（双击“声音控制器”提示没有活动的混音器可以使用），有各种警告音，但各种媒体都播放不了。其他一切正常。

郁闷！ 这是什么原因造成的呢，该如何解决呢？请各位大侠出手相助，在下不胜感激……

说明一下，我的xp－2系统是自动升级补丁的


按照 电脑侠客 的指示，用HijackThis1991修复、扫描结果如下，望各位大侠相助！

用HIJACKTHIS修复以下项：

如果存在C:\WINDOWS\system32\winmsd.dll，请删除

另外请搜索一下你的磁盘中有几个svchost.exe文件，其版本，文件大小和属性贴上来。（截图）

怎么发图呀？Mƒˆ÷¨¿$U bbs.ikaka.com3¨X̦E§‡š°

搜索结果：Mƒˆ÷¨¿$U bbs.ikaka.com3¨X̦E§‡š°

你查看一下每个svchost的版本及公司信息。应该都是microsoft的程序。然后再看一下系统还有什么问题Mƒˆ÷¨¿$U bbs.ikaka.com3¨X̦E§‡š°

三个文件只有版本不同，公司都是Microsoft Corporation，产品名称都是Microsoft® Windows® Operating System
系统除了不能播放媒体（各种警告音都正常），其他都正常……
出现错误警告之前能播放媒体，出现后，点击“取消”便不能播了。
还有，第二个文件不知是什么东西……？
