Unable to remove Bitcoin Miner

[Aiden2k13]

Hi, I have KAV 2015 installed with latest updates and just out of curiosity I installed MalwareBytes and it picked up Trojan.Bitcoin Miner in svchost. I am on Win 8.1 pro . Malwarebytes scanned and I selected remove items and it asked me to restart PC for the removal process . So I restarted and out of curiosity I rescanned and it found those bitcoin trojans again and I again removed it and restarted PC and then rescanned again and it picked those bitcoin trojans again.
How do I get rid of it ?
Here is the threat log : Link

I formatted my PC and its gone now.
Any idea on which security should I install now to prevent it from entering again ?

bitdefender is my choice

and its as important how you surf as what security software you use-- usually get stuff like that by clicking on stuff you shouldnt especially on facebook as with that many users some one is bound to click things they think look interesting
