病毒名称: Worm.Netsky.c 中文名称: "网络天空"变种 威胁级别: 3A 病毒别名:W32.Netsky.c@MM [Symantec] I-Worm.Moodown.c [Kaspersky] WORM_NETSKY.C [Trend] 病毒类型: 蠕虫 受影响系统:Win9x/WinMe/WinNT/Win2000/WinXP/Win2003
此次变种会继续大量发送病毒邮件，并且邮件主题、内容以及附件名称改头换面，使人更容易上当。更恶毒的是，它会搜索受感染系统的A 到Z盘，查找名字包含"shar"的文件夹，如果查到，它会释放一个病毒复本，使用工具软件和破解软件的名称。这样使病毒具备了通过P2P软件 传播和通过局域网共享传播的能力。而那些具有欺骗性的病毒复本名称使人更容易中招 。病毒的大量感染会造成更大量病毒邮件在网络中疯狂传播，严重浪费网络资源，最终导致邮件服务器极不稳定，甚至瘫痪，对企业用户的危 害十分大。 金山毒霸于当日完成应急处理，升级了病毒库，请升级到2004年2月26日的病毒库可完全处理该病毒。使用毒霸的用户请注意开启邮件防火墙 和病毒防火墙来防止病毒的入侵。以下是病毒的技术特点：
· 将自己拷贝到 %Windir%\Winlogon.exe，病毒进入系统后所存在的位置；
· 在以下主键 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run 添加以下键值 "ICQ Net" = "%Windir%\winlogon.exe -stealth" 以便病毒可随机自启动
· 在%Windir% 目录下生成ZIP包，包内就是病毒复本，病毒会将此包做为邮件的附件；
· 如本地系统时间在 2004.2.26 上午 6:00 到上午8:00间时，蠕虫将导致计算机将不停的响铃。
· 在所有非光盘的分区中检查包含“shar”字样的文件夹，然后将自己以下列可能的名字拷贝到 找到的文件夹中,使病毒具备了通过P2P软件传播和通过局域网共享传播的能力：
