Watching a series on Netflix and the sound goes down all by itself… I turn on full again and a few seconds later he goes down again! 5 seconds later, 15 seconds later…
I'm a little worried now What could that be? Has one hacked my laptop?
Unlikely could be the film / series or the laptop but so boring would be no hacker to turn only louder and quieter
I can't tell you what it is, but I doubt you were hacked.
A hacker actually wants to go undetected so he can access your saved passwords. It makes no sense if he is so conspicuous and gets caught.
Nevertheless, I would scan the laptop with Malwarebytes and ADWcleaner.
Maybe it's because of the operating system or something like that. Is there an update?
