Windows host process/bluetooth pops up every time I start an executable file

This is very weird.

I came to visit my parents and loaded up the computer. I normally use Ethernet cable for network connection at home but here it’s a wifi wireless system. Everything has usually gone smoothly

but this time I noticed that everytime I launch a video game (an executable)file a bluetooth window pops up. The window is “received files”-window and has a bluetooth logo on it. But there’s nothing else on the window, no received files, nothing. It’s kind of a bluetooth file log but the log is empty.

I tried to see if bluetooth machines nearby were responsible for it (disconnecting one bluetooth machine from bluetooth) but nothing happened. After that I started up and disconnected my computer’s bluetooth. This didn’t change anything, the bluetooth pop up still come (on the task manager it says Windows Host Process, and when you double click → Received Files (with a bluetooth logo). When I quit the bluetooth window it disappears from the task manager, but the window comes back when I launch another exe.file.

What is this, why does it appear when I launch an executable and why has it begun acting just now?

Computer is Windows 8.1

Thanks.

Update:

I did a scan on both Malwarebytes and after that Avast.

While I was scanning with Avast the problem disappeared. The bluetooth window kept no longer coming.

However, when the Avast scan was finished (it was clean), I closed it and started playing again. Upon doing this I noticed that the Avast program had reopened itself.

My hypothesis:

Whenever I open an executable file it opens the previous executable file I’ve used, in this case bluetooth window (as I had plugged in my bluetooth headphone upon starting up the computer) and after that Avast (as I had just did the Avast scan)

Going to reboot my computer and see if it fixes the issue. I have never stumbled upon this kind of a problem before.
