For me windows defender turned off when I downloaded mcaffy and didn’t turn back on when I turned everything off in mcaffeyand later uninstalled it cuz I had run out of subscription but it also works with malwarebyte (I think that’s the name) which is free. And it is only a firewall so it won’t uninstall things unless u tell it to. 
 
I hope this helps you. 

Your RAM is quite a big problem too. Ryzen loves memory bandwidth and frequency, but yours has neither (not even dual channel)
