How to use?
When you download and extract you'll have an .exe file, simple start it. This screen will show up:

Now you can start Modern Warfare 3. The first window will close and the main cheat will show up.
For security reasons its recommended to start the cheat first, and then the game. But it will work the other way round as well.
Now if you either close your game or it crashes, the main cheat will close and the first window will appear again. You can start you game again and the main cheat will show up again, or you can simply close the cheat by clicking the "X"-Button in the right up corner.
Red marked functions?
Sometimes you will notice that some functions (NoSpread, Speedhack, ...) are red. That happens when you are NOT HOST but the functions requires you to be host. This is just an information for you, you don't have to do anything. The function will be disabled until you are host again.
VirusScans:
VirusTotal
Jottis
A few false positives due to cryption with .net layer anti-dump confuser
If your antivirus detects it, turn it off or add the file as exception. If you don't trust me, simply don't use the hack^^
