There are much better alternatives for CPU-mining.
I'd recommend checking for coins using the Argon2d-algorithm like Credits (CRDS), Dynamic (DYN) or Nimiq (NIM).
According to my experience I'd say Nimiq is the most profitable "CPU-only coin" currently (just make sure to use the external miner and not the browser-mining).

There may be more profitable alternatives I haven't tried yet.
thanks I would check it out tommorrow. I use a virtual box for linux.
