Mw2 Mutiplayer Crack Help

I have tried multiple cracks and keygens and nothing is working to play online...
Any help on working cracks would be greatly appreciated!

first, i would scan ur whole pc, as u have used keygens, which almost always contain a virus (the mw2 keygens i mean). and for now, there are no working cracks for the game, just buy a cheap key

True, thanks. The only keygen I have used is the razor 1911 ver2.0
I will scan my pc though.
