Can you play the file? It might be a virus.

I think it's a virus. Check for viruses using the built-in antivirus in Settings > Battery and device care > Device protection, or use third party antivirus apps like Malwarebytes or McAfee.

Hi, Carlosology!

According to this YouTube Music forum, this specific file isn't a virus but a system file that might have come from different apps. The usual apps where this file came from were YouTube Music, Samsung Music, or Pinterest. But it can still come from different apps not mentioned here.

Since this is a system file, you can't really delete it or prevent it from appearing in your files/folder unless you open your apps one by one and check if an app triggers the creation of the file.

Rest assured that this is not a virus but only a system file that's saved as an mp3 file.
