X-Fire what's it do?
 

I seem to have downloaded this along with Game Booster( which I can figure out, )but for the life of me cannot figure out how it works or what it does in relation to CloD ( or anything else..) I can't seem to get rid of it either.Assuming it has some use- can someone help me out?

If you mean what i think you mean, it's some kind of multiplayer match-making software like Hyperlobby.
