How to avoid, remove Facebook malware:
Cnet: "On Facebook, there are a few different ways your account, privacy, and computer can be compromised.

Other times, the app that promised to be a "dislike" button will instead download and install malware on your computer."

This is why I don't play free games and trivia stuff on facebook. Just say NO.
