On Windows 10, Microsoft Defender (formerly called “Windows Defender”) always scans files before you open them unless you’ve installed a third-party antivirus. You can also perform a quick scan of any file or folder, too. Here’s how.

在Windows 10上，除非安裝了第三方防病毒軟件，否則Microsoft Defender (以前稱為“ Windows Defender”)始終在打開文件之前先進行掃描。 您也可以對任何文件或文件夾進行快速掃描。 這是如何做。

First, find the file or folder you’d like scan. It can be located within File Explorer or on your Desktop. Using your mouse cursor, right-click on the item.

首先，找到您要掃描的文件或文件夾。 它可以位于文件資源管理器內或桌面上。 使用鼠標光標，右鍵單擊該項目。

In the menu that pops up, select “Scan With Microsoft Defender.”

在彈出的菜單中，選擇“使用Microsoft Defender掃描”。

(On versions of Windows 10 prior to the May 2020 Update, this option will say “Scan With Windows Defender.”)

(在2020年5月更新之前的Windows 10版本中，此選項將顯示“使用Windows Defender掃描”。)

A Windows Security window will pop up, and the results of the scan will be shown near the top—just below the “Scan Options” heading. If everything is OK, you will see “No Current Threats.”

將彈出一個Windows安全性窗口，掃描結果將顯示在頂部附近-“掃描選項”標題下方。 如果一切正常，您將看到“沒有當前威脅”。

On the other hand, if malware is detected, Microsoft Defender will alert you with a message that says “Threats Found,” and it will list the file or files that are infected.

另一方面，如果檢測到惡意軟件，Microsoft Defender將通過一條消息“發現威脅”來警告您，并且它將列出被感染的文件。

To remove the threats, click the “Start Actions” button.

要消除威脅，請單擊“開始操作”按鈕。

After clicking “Start Actions,” Microsoft Defender will remove the threats automatically, and everything should be back to normal. If you’d like more details on what threats were neutralized, click “Protection History” just below the scan results.

單擊“開始操作”后，Microsoft Defender將自動刪除威脅，并且所有內容應恢復正常。 如果您想了解有關消除了哪些威脅的更多詳細信息，請單擊掃描結果下方的“保護歷史記錄” 。

Good luck, and stay safe!

祝你好運，并保持安全！
