This is a nightmare. There's a virus in the house. My personal computer caught it while browsing on the public access network. I come home and the living room is a sauna, the bedroom windows are covered with ice, the refrigerator has defrosted, the washing machine has flooded the basement, the garage door is cycle up and down and the TV is stuck on the home shopping channel. Throughout the house, lights flicker like stroboscopes until they explode from the strain.
Broken glass is everywhere.
Of course, the security sensors detect nothing. They think they've digitally disinfected the house, but the place is a shambles. Pipes have burst and we're not completely sure we've got the part of the virus that attacks toilets. That one is really evil. Everybody's very, very, sorry, but they can't be expected to anticipate every virus that might be created.
