A few weeks ago, I experienced something very creepy on my laptop. Whenever there was a slight period of inactivity or even creepier, when I stepped away from the screen, my laptop would automatically start performing strange, unexplained actions. A new tab would open, weird text would be typed on it, and the list of available Wi-Fi networks would often be explored. I’d frantically close the strange tabs, disconnect the Wi-Fi, or restart my laptop.
