Plutonium

Dss0 I used webroot, but uninstalled it, I've repaired the files already. I own the game so it's through steam: C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Black Ops II

When I go to launch the game it loads for a second, freezes, then closes without opening the game. I've uninstalled my AV, I've excluded plutonium in my settings, I've downloaded DirectX and all that other stuff and it's doing the exact same thing. Please help.
