Very nice question! With a little thought, I was certain about the answer. While this was the first time I heard about "halloween protection", the chain of thought I used was Halloween = ghosts & goblins. Ghosts = phantom. We all know about "phantom updates" and hence the answer had to be what it is.

This one has to be the best of the fun series - simply because it teaches something new. Further reading into "Halloween protection" gave me some great insight into what it really is and how can we prevent it.

Happy Halloween, everyone! (And for those who got caught in the storm, I pray that you did not face any major losses).
