May I ask if you use Google Chrome to access Facebook?
I ask you this question because last week this browser has problems to visit Facebook due to its internal error. It is very unstable that it could open successfully for a quarter of hour, but suddenly became white colour and it could not be collected any more. All other browsers have no problem and could still reach Facebook smoothly.
However, the problem was settled and I believe when you read this message right now, you can access Facebook properly for the time being. Don't worry. It is not about the problem of your computer or any anti-virus software.
Hope I can help you.
