请问netservice526.dll是什么东西?

问题
-
最近好多台机子出现类似的情况,机子会自动往注册表的\MACHINE\software\microsoft\windows nt\currentversion\winlogon\notify下面添加一个叫netservice526的键,其中有一个DllName的键值是c:\program files\netmeeting\netservice526.dll,请问这个netservice526.dll是什么东西呢??另外,不同的机子添加的这个键值不一样,主要在后面的数字不一样,比如有的是netservice214,有的是netservice642等等,这是病毒吗??还是说netmeeting本来就有这东西?谢谢

If you are using an Engine older than what is current, we strongly recommend that you upgrade as, in a lot of cases, an old engine will not identify and remove certain malware (even with a current set of DAT files). So, as well as DAT files, engines need to be updated to include regular changes and improvements made to the scanner.

从路径上看,它应该是系统自带的Netmeeting的一个动态链接库文件,如果你不放心,可以把文件上传此地址进行分析:http://www.virustotal.com/zh-cn/

我上http://www.virustotal.com/zh-cn查过netservice526.dll这个文件了,有16种杀毒软件报告这是病毒。搜索网上基本上都是说netservice.exe这个病毒的,但是没有发现一个netservice526.dll的。而且这个文件是在c:\program files\netmeeting下面,很诡异。

好的,下面是扫描结果。不过没法贴图片哎,搞得排版很乱,没办法,将就着看吧。病毒文件名是netservice526.dll。
反病毒引擎 版本 最后更新 扫描结果

另外还有个奇怪的现象,很多机子的mcafee都报警是有程序往注册表写如一些东西。写入的键和上面的很类似,都是下面这些。不过哪个文件就不一定。
