On August 1, bitcoin was forked, and the new currency was called bitcoin cash. Everyone who had bitcoins before the fork now has the same amount if bitcoin cash as the amount of bitcoins they had. (If i had 0.01 btc before the fork, I would get 0.01 bcc). The BCC are on the same addresses as the btc.
Claiming your BCC is a bit complicated, but you basically create a new wallet for the btc and export the privates key of the original btc wallet to BCC wallet.
