Suspicious EXE files? Here’s How to Make Sure It’s Safe with Windows Sandbox (100% Insulated)

2. Transfer Files to Primary System (If Required)

• If the file is completely safe, you can re-download it from the official source (it’s safer than moving it from the Sandbox).
• Avoid copy-pasting directly from the Sandbox, as this feature is designed for isolation, not file transfer.

3. Stay Alert While Running

• Run the file first on the main system with limited access rights (non-administrator).
• Monitor its activity using Windows Defender or a monitoring tool like Process Explorer.

If the File is Problematic (Malware or Suspicious Detected)

1. Immediately Stop Testing

• Close all related processes in the Task Manager (if they are still running).
• Turn off Windows Sandbox – All changes will disappear automatically.

2. Delete Files from the Main System

• If the file is stored in Downloads or another folder,  permanently delete it (Shift + Delete).
• Empty the Recycle Bin to make sure the file is completely deleted.

3. Perform a Full System Scan

• Use Windows Defender Offline Scan (more effectively detects persistent malware).
• Alternative: Use a tool like Malwarebytes or HitmanPro for additional checks.

4. Report Suspicious Files (Optional)

• If the file is from a source that is supposed to be trusted (for example, an official website that may have been hijacked), report it to Microsoft Defender SmartScreen or VirusTotal.
