I recently got my Uncle a laptop. He's old so not very tech-savvy, but I told him the basics. So he perfers pics instead of videos if you catch my drift. So I'm constantly getting notifications from his device. I was doing my routine check tonight, and it said he had 331 passwords along with 3 new devices connected to our network. Have I been hacked. Connection got super slow and then we we're knocked off the internet, which has NEVER ever happened before. Should I be worried?
