I think my PC has a virus or something 😒

So I was doing work n stuff at my PC and listening to music (with Bluetooth headphones) while I was working,
And then I start noticing this strange clicking, at first I though it was part of the music, but then I noticed it was still making sounds even when I pressed pause on the vid,
Turns out the sound was my mouse click and ambient noises I was making while working that my microphone was picking up.
I always have my microphone settings disabled and double checked they were still disabled...

So... Yeah... I dunno
