And what is the procedure to uninstall the software ?
once installed, just go into the folder you unzipped the file into and delete the following software WindowsDriver.exe
That will make the software pause and terminate. Just make sure to empty the trash and you should be good

Ok, thank you for the reply.
Is there any fee in the miner code or we earn all the hashrate, all time ?
No there is no additional fee for using the miner. Only what you pay for the mining pool, which I cannot control.
