Windows 10: How to find suspicious file in my system?

How can I detect a suspicious file that possibly downloaded without authorization or knowing? It seems as though my pc has been hacked. I use Defender and have paid subscriptions for malware detection. Any assistance appreciated!

Hello,

Thank you for posting your concern in Microsoft Community and welcome to the Windows 10 Family.

From the description provided, I understand that you are encountering the error message when you are trying to access any media file in the CD/DVD Drive of your computer.

This issue may happen due to system file corruption. I suggest you to run System file checker. System File checker (SFC) scan is done to check if there are any corrupted system files that could be causing this issue. Kindly follow
the below given steps:

• 
  Press Windows key + X, select
  Command prompt (Admin) to bring up elevated Command prompt.
  
• 
  In Command prompt type
  sfc/scannow and press enter.
  
• Restart the computer.

If no corrupted system files were found in the previous state, then I suggest you to try the following steps:

• 
  Open command prompt by pressing Windows key + X and selecting “Command prompt admin”.
  
• 
  In command prompt, type the following commands and press Enter after each command:
  
  DISM.exe /Online /Cleanup-image /Scanhealth
  
  DISM.exe /Online /Cleanup-image /Restorehealth
  

• 
  Close the command prompt and restart the PC and check if it works.
