Coinhive
You should check out WebMinePool! They pay a flat rate of 210 satoshi per one million hashes while Coinhive consistently pays 15-20% less than this (WebMinePool's payouts are supposed to raise even more this weekend). WMP also offers payouts straight to FaucetHub. This means no exchange fees, no dealing with wallet fees, none of that stuff. It's way better than Coinhive. You should check it out!
I know them, the problem is that their miner is detected and blocked by 99% of antiviruses
That's odd, I would think Coinhive is blocked by more anti-virus programs because of its size. WebMinePool is new. I use WMP on my site and never have I once had my browser tell me "this site is unsafe." I have never gotten a report of this from any of my users either.
