按照该软件说明，”O10 - Unknown file in Winsock LSP: c:\winnt\system32\cdnns.dll“是否有问题？我用该软件进行修复，可是却没有效果！是这个问题吗？如果是，应该直接删除这个cdnns.dll文件吗？
请这里的防病毒专家帮我分析一下，谢谢！

这三项我用了”修复“功能，但修复010这一项时提示要重启电脑，但重启后扫描后又出现了，网页还未修复。。。。。。

如果使用了系统还原，请先关闭。
请关闭所有浏览器窗口和文件夹窗口, 在安全摸试下修复上面项)（如果你清楚某项是安全的，可以不处理）
，将隐藏的文件不隐藏。找到下面项C:\WINNT\MSNMSGER.EXE
把它删除。
