make no sence
you cant put the game inside the search because of his size, 650 mo is the limit (and most data are more heavy than that)
plus all link to dwl are safe for your website
so yeah you make no sence
well i think it's a error, cause first it not the only one that appear as that (exe file i mean), and some are from more than 1 year ago
so yeah if it was really virus i would say that i would have some bad new, crash or whatever, and nothing of that sort, so yeah, and even game like rainbow 6 siege got blocked sometime and classified as infected with bad malware, virus ... so yeah dont bother yourself too much with that
