Virus Z was a maze at Knott's Scary Farm's 40th Halloween Haunt back in 2012. It was mostly about The Walking Dead taking over the once charming town of Pleasanton, and turning it into a grotesque, horrible nightmare. But at the end of the maze there was a special "Prom Scene" finale from the film Carrie. This was because Sony Pictures approached Knott’s and asked if they could help market and reboot the film that they were about to release. Which they excepted
- While you would walk though the maze of "The Prom Scene" you would hear the sounds of people screaming crying and screeching.
- You would also hear the voice of Margaret White sing the song "Let The Lower Lights Be Buring" by Johnny Cash.
- The Maze was at Knott's Scary Farm's 40th Halloween Haunt from September 21st to October 31st, 2012.
