Binary Erinyes

A virus infected my computer, and a girl appeared on the desktop. She eats, sleeps, and plays, and when she gets hungry, she casually gobbles up the nearest icon. So every day I have to prepare a bunch of shortcuts for her to eat. Sometimes she gets bored and shakes the screen. If I don't play with her, she keeps shaking my windows and even starts programs without permission. The most infuriating thing is that if I use the computer too late, she shuts it down automatically, saying I'm keeping her awake. She doesn't show up in Task Manager, no antivirus program can remove her, and she doesn't appear in the startup list either. But apart from that, she hasn't caused much trouble, so I've just let her carry on like this.
