被侵犯的計算機會類似於這些照片:
注意背景被更換，安全中心被關閉, 而且會跳出窗口讓用戶填寫信用卡信息！[/COLOR][/SIZE]

[B]測試你的系統是否會中毒!!!

右鍵單擊, 下載下面文件, 雙擊下載后的文件. 你會發現"Calc.exe"被打開, 然後跳出Explorer錯誤"Run DLL as an App".

如果有上述情況, 你的電腦就有中毒可能.

剛果本人已經測試過, 除測試系統是否會中毒外不會對系統有負面影響.

解決方式:
1. BackChina主頁所提到的避免方式已經不能緩解最新版的病毒/惡意軟體
2. 暫時最新和最完全的解除方式, 下載並安裝下面任何一個exe文件, 等待微軟發布正式補丁時再用程序卸載中心卸載此軟體
