I'm not familiar with how Malwarebytes works. Anyone know what basis they block things on? Is it user reports or something technical?
malwarebytes blocks alot of sites and issues warning for literally a dozen of legit programs on my PC
any Autoit script it considers to be a major trojan horse,so I would not be too concerned about it
the heuristics finds something on the site that matches their patterns,cannot really say what that is-mining,any leftover code,any i-frames could be a culprit
maybe from the times when the site had banner spaces
the best way is to contact them as an owner and try to find out
