这项是灰鸽子，参考http://forum.ikaka.com/topic.asp?board=28&artid=7713905，若还解决不了再跟帖。

O23 - Service: Network System (Universal Disk Manager) - COMENET TECHNOLOGY - C:\Program Files\Common Files\COMM\Network.exe
这一项，用与灰鸽子类似的方法删除其注册表项，然后重启电脑后删除C:\Program Files\Common Files\COMM\文件夹。

问题解决了鸽子变种很多，查杀方法各异。本帖只适用于下述情形：

（1）杀软报告灰鸽子但杀不净；且（2）HijackThis日志中发现异常O23项（如：O23 - Service: svchost (Windows Access) - Unknown owner - C:\WINDOWS\windr.exe）；且（3）灰鸽子的文件在%windows% 目录下。

这类灰鸽子的手工查杀流程：

1、打开注册表编辑器，展开：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services。删除灰鸽子的服务项。
怎么确认灰鸽子服务项的名字？看HijackThis日志O23的提示。如：O23 - Service: svchost (Windows Access)，括弧中的Windows Access就是你要删除的灰鸽子服务项。
如果HijackThis日志O23的提示中没有括弧中的内容，紧接在Service:后面的内容就是灰鸽子的服务名——删！
有人可能会问：这是不是笨了点儿？在HijackThis面板中直接点击这个O23，再点击“修复”不就完了吗？
是的。我也知道有此一法。但这种方法并不能保证你总能修复掉这个异常的O23。最后，还是要用注册表编辑器删除它。
2、重启系统。为什么要重启？ 因为这类鸽子没有注册表监控。删除其服务项后，重启系统，鸽子就不能运行了。这时，鸽子的文件可以随便删。

3、显示隐藏文件，删除鸽子的文件。
这类鸽子的文件都在%windows% 目录下。%windows%是什么意思？%windows%是个变量符号，表示“WINDOWS”目录。因为每个人的系统不一定都安装在相同的分区，因此，只能这么表示。如果你的系统安装在C盘，%windows%指的是C:\WINDOWS；如果你的系统安装在D盘，%windows%指D:\WINDOWS，依此类推。

怎么确认鸽子的文件名？还是看HijackThis日志。Unknown owner - 后面的内容就是鸽子文件的所在位置及其文件名。本例是C:\WINDOWS\windr.exe）。

注意：除了可执行文件.exe外（本例是windr.exe），%WINDOWS%下可能还有包含可执行文件名的.dll文件（以本例为例，这些dll的文件名可能有windr.dll、windr_hook.dll、windrKey.dll），这些文件数目不定。只要有，也要删除。
