My windows get hacked

Question

Hello, today when I turned on my computer, I heard music in the background, the sound of keyboard keys and a clicking mouse. What can it be, did I get hacked? How to know and how to fix the problem so that it does not happen again. For information I use the free version of avast antivirus.

Thx

Before you go through the pain of reinstalling Windows you might want to try the MS safety scanner.

And a Defender boot time scan.

And run whatever full scan option Avast provide.

I heard music in the background, the sound of keyboard keys and a clicking mouse.

Are you sure that you didn't just have a web browser open and some video was auto-playing? Your comment implies that the microphone of the hacker's PC is being broadcast to your speakers. While I guess that's not impossible, I would think that's highly unlikely. If true, the guy's a bad hacker and you should be able to detect the malware.

Did you install anything recently?
