从昨天开始，电脑突然开始自动安装一系列流氓软件。我一一卸载后，又偶尔弹出一些网站。用Hijack修复过一点后，问题还没解决。
请帮助看一下扫描日志：

下载，LSPFix.exe，WinsockXPFix这两个软件
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LSPFix.exe
删除
wshcon32.dll

附说明一份
LSPFix.exe这个软件主要用来辅助修复HijackThis扫描发现的O10项。
使用时，请关闭所有IE界面和文件夹界面后运行LSPFix，运行后，把要修复的那一个O10项从左边转到右边，点“Finish”即可。（不过这之前，需要在“I know what I`m doing”前面打勾。）
双击我的电脑，工具，文件夹选项，查看，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。在提示确定更改时，单击“是”，清除“隐藏已知文件类型的扩展名
删除
c:\windows\system32\wshcon32.dll

到添加删除里面卸载掉MMSASS~1
重启到安全模式下删除
C:\PROGRA~1\MMSASS~1
C:\WINDOWS\Rundll32.exe这一项先结束进程
