Overview
A guide showing what *might* be causing this. (Please note this is just for freezing (black screen) and NOT the memory error or infinite loading bug many are getting.)

Does your options menu freeze right after you try to change things?
Do you really want to pick your suit but can’t ‘cus it freezes?
Fed up of watching that intro video for the 5th time when all you wanna do is ♥♥♥♥ up some zeds?
If yes to all of the above then you are (probably) in the right place. I too have experienced this first hand and the first thing I did was look at the guides section only to find no-one has wrote one yet (which considering how many people are asking about this, is pretty surprising).
What’s Causing It Then?
It seems that some Anti-Virus software absolutely hate this game, especially AVG. They don’t like it when you try changing anything in the game via options and loathe it when you try to actually get into a game. The fix that worked for me and many others is to make the game an exception in your Anti-Virus.
How To Make An Exception (AVG)
Firstly load up AVG, click “Options” and then “Advanced Settings”
Next up click “Exceptions” on the left side bar, then “Add Exception” on the bottom right
Now select the drag down tab and click “Application or File”, then click Browse on the right hand side
Now find the game file, this will vary depending where you have installed your Steam games. It is usually located in :-
C:/Program Files (x86)/Steam/SteamApps/common/Call of Duty – Inifinte Warfare/iw7_ship.exe
Once you have added it to the list of exceptions, confirm it and then that should be it.
Hopefully this will help many of you that are experiencing this problem.
