望高手帮帮我。

运行hijackthis，把下面的选中打上钩，修复

O10 - Unknown file in Winsock LSP: c:\windows\system32\quartz32.dll
O10 - Unknown file in Winsock LSP: c:\windows\system32\quartz32.dll

请下载LSPFix和WinsockXPFix这两个软件，它们在：
[必读]本版说明及常用小软件下载

http://forum.ikaka.com/topic.asp?board=67&artid=5188931
　　重新启动电脑, 进入安全模式。运行LSPFix.exe，删除：
quartz32.dll
说明：
LSPFix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。修复后重启计算机，如果无法上网，请运行WinsockXPFix，让它修复一下。

O2 - BHO: NaviHelperObj Class - {3E422F49-1566-40D3-B43D-077EF739AC32} - C:\WINDOWS\NaviHelper.dll

1.在命令行窗口，用 regsvr32 /u Navihelper.dll 命令，先将此dll卸载。
2.将位于 %System%/Windows/System32/ 的 host.dat 和 navihelper.dll 两个文件删除。
3.在 %System%/Windows/System32/ 目录下，新建两个文件，文件名为host.dat和navihelper.dll，并将这两个文件设置为只读即可^_^。

问题解决了.谢谢高手!
