二、解决方案
辨别病毒程序
在进行病毒清除前，首先辨别该病毒程序。
- 使用趋势科技的防病毒产品扫描你的系统
- 记录下检测出的所有 WORM_NETSKY.C 文件
趋势科技的用户在扫描系统前应该下载 最新病毒码 。其它的网络用户可以使用趋势科技的 免费在线病毒扫描器 Housecall。
结束病毒程序
该操作结束内存中运行的病毒进程。你需要刚才记录下的文件名。
- 打开Windows任务管理器
在 Windows 95/98/ME 系统上, 按下
CTRL+ALT+DELETE
在 Windows NT/2000/XP 系统上, 按下
CTRL+SHIFT+ESC, 并点击进程标签
- 在运行的程序列表中，找到刚才记录下的病毒文件：
- 选择病毒进程，根据系统的Windows版本，按下结束任务或结束进程按钮。
- 对运行进程列表中的其它病毒文件执行相同的操作
- 关闭任务管理器，再重新打开，检查病毒进程是否结束
- 关闭任务管理器
*注意: 系统上运行的如果是Windows 9x/98/ME, 任务管理器可能不会显示某些进程。你需要其它的进程管理器来结束病毒进程。否则，继续下面操作的同时，注意附加提示。
从注册表中删除自动运行键
删除注册表中的自动运行键可以防止病毒在每次系统启动的时候运行：
- 打开注册表编辑器。点击 Start>Run, 敲入 Regedit,然后回车
- 在左边的面板，双击下面的项目：
HKEY_LOCAL_MACHINE>Software>Microsoft>
Windows>CurrentVersion>Run
- 在右边的面板中，找到并删除下面的键：
ICQ Net = "%Windows%\winlogon.exe -stealth"
注意: %Windows% 是默认的Windows文件夹，通常是 C:\Windows 或 C:\WinNT.
- 关闭注册表编辑器
注意： 如果按照上面操作仍不能结束内存中运行的病毒进程，请重启你的系统。 运行趋势科技防病毒产品
使用趋势科技的防病毒产品扫描所有文件并删除检测出的 WORM_NETSKY.C 文件。趋势科技的用户在扫描系统前应该下载最新病毒码。其它的网络用户可以使用趋势科技的免费在线病毒扫描器 Housecall。
