當開啟硬碟時，出現"選擇您想要用來開啟檔案的程式"?

在「我的電腦」裡，點下「本機磁碟 (C:)」來開啟..(圖下紅圈)


出現"選擇您想要用來開啟檔案的程式"? (圖下紅圈)


原因是什麼?

答案：中了Auto Run 病毒 & kavo 病毒
說明：除了網路磁碟機外，這個病毒會在每個可以有效寫入的磁碟機代號的 \ 處寫入autorun.inf、ntdelect.com 兩個檔案，並將檔案屬性設定成唯讀、隱藏、系統。病毒檔 ntdelect.com 與 XP 系統檔 ntdetect.com 檔名類似。中間的 l 與 t 僅一個字母的差異。誤刪系統檔的話會不斷重新開機。
檔案名稱比較:
病毒檔 ｎｔｄｅｌｅｃｔ．ｃｏｍ
系統檔 ｎｔｄｅｔｅｃｔ．ｃｏｍ

它會在 C:\Winddows\System32 中，留下兩個駐留檔案，分別是 kavo.exe、kavo0.dll 兩個檔案，並將檔案屬性設定成唯讀、隱藏、系統。那個 KAVO.EXE 則是仿知名的防毒軟體 KAV 而來，實際上防毒軟體 KAV 的執行檔不見得就是 KAV.EXE 而是其他的檔名。

我該如何解決問題?
請把如下紅色部份的文字複製起來，貼在記筆本上，然後按「檔案」→「另存新檔」
檔名後面的.txt改成.bat→再按「存檔」。 如：自動清除執行檔.bat
