I think the reason why some antivirus or systems detects mining software as viruses is because it manages the performance of the hardware, specifically, the graphics card or video card needs to function too much in order to mine cryptocurrency. So the best way to just shut the warning off is to turn off the protection when you are running the mining software.

But make sure that you have the proper hardware to mine cryptocurrency, because most of the time before, many just surf the hype of bitcoin mining, they have converted desktop pc's to mining rigs which isn't the proper way to mine, as it consumes more energy/power, in the end, instead of gaining profits, you lose because of the electricity bill.
