I've found one of the best Programs to use your own PC as mining power to mine yourselves some BTC. Now this software is very easy to use and free to download because i also got it for free so i wouldn't charge. You can download it free on any btc forums 2 but your gonna have to search a bit.

U can also download it free her at speedy share.
you should also run a virus scan just in case if you feel threatened in any way.
I can only speak for myself that it has worked for me and i dont mine much but i mine 0.01 everyday ten days i got myself 0.1 and in 100 days i got 1 bitcoin.
