用到 http://endurer.ys168.com 下載 IceSword檢查進程，發現還有一個隱藏的IE進程。

終止病毒進程。

停止並禁用O23中的服務。

到 http://purpleendurer.ys168.com 下載 FileInfo 和 bat_do。用FileInfo提取檔案資訊，用 bat_do 將病毒檔案打包。

下載 Dr.Web CureIt（和使用方法可參考：
免費的惡意程式檢測和清除工具---Dr.Web CureIt! http://endurer.bokee.com/5488502.html），因為時間關係，只掃描 c:/windows 和 c:/Documents and Settings，結果……明天補上。
