近日在网上相续看到有网友表示自己在下载使用了VeryCD下载链接查看器这款工具以后，再打开浏览器就被直接跳转到 http://www.2345.com/?kunown 这个导航页面了，而且打开多个浏览器：IE、Chrome、Firefox、Opera、Safari、Maxthon，均相同症状，检查浏览器首页设置——均正常！ 最后发现，原来快速启动栏的IE浏览器快捷命令被其修改，修改后的类似如下图，于是认为就是普通的修改快捷方式，手工删除 2345 网址的部分，但半小时后再次被更改了。考虑到可能加载了启动项，在注册表、启动项、服务等中均未查找到相关信息，重启后IE快捷方式被重新篡改。尝试了事件查看器和任务计划，均未在里面查出任何信息。
之后又安装了超级兔子、360、exterminateit等工具进行检查，也未检出。 打开ProcessMonitor进行监视，发现每隔30分钟出现一个scrcons.exe进程自动启动并修改快速启动栏的命令，然后自动关闭（幸亏是30分钟一次，你要是24小时一次，那我就杯具了…），修改Win7下opera快速启动图标路径类似如下： C:UsersiefansAppDataRoamingMicrosoftInternet ExplorerQuick LaunchUser PinnedTaskBarOpera12.01 1532.lnk 查找资料，发现这应该是一个通过WMI发起的定时自动运行脚本。要查看WMI事件，到以下地址下载WMITool并安装http://www.microsoft.com/en-us/download/details.aspx?id=24045 安装后打开WMI event viewer，点击左上角register for events，弹出Connect to namespace框，填入“rootsubscription”，确定，出现下图：
点击左侧_EventFilter:Name="unown_filter"，再至右侧右键点击ActiveScriptEventConsume r Name="unown"，选择view instant properties，如下图：

最后，清除方法：在WMI event viewer中将“_EventFilter:Name="unown_filter"”项目右键删除！ 删不掉？ 到WMITool安装路径（例如：C:Program Files (x86)WMI Tools）下，右键点击wbemeventviewer.exe，选择以管理员身份运行！删之！ 还没完，还要手动将快速启动栏中，将各个浏览器快捷命令中的http://www.2345.com/?kunown去掉！ 暂时就这么多了，还有没有其它影响的话，用用再看吧！ 解决方法来自：Gemini
希望大家能够把这解决方法普及开来，现在大多人还是用修改快捷方式之类的解决方案，已经落伍了...
