Since past few days I have been witnessing a really annoying or rather a creepy thing on my Dell Inspiron Windows 10 computer. Sometimes, after I switch on my computer, it starts playing a music clip which is around 10 seconds long. I don't understand how is it happening. I am certain that I have not installed any such thing my computer (at least knowingly). Few things to note,
There are two such music clips. Either of them gets played or sometimes both of them gets played one by one.
Sometimes the clip is played 1 time, sometimes 2 or 3.
There is no fixed time. Sometimes it gets played after 5 minutes of starting my computer, sometimes 15.
I have checked and I am certain that my browser is not causing it. In-fact, it gets played even when there are no open applications on my computer.
It does not happen every time I switch on my computer.
Is it possible that my computer has been hacked or there is some sort of malware that is doing this. I know it sounds really silly but still it is really creepy and I want to know what is causing it.
