I'm kind of leaning towards Microsoft's recommendation when something doesn't work with Edge; use Internet Explorer. It definitely explains why they ship with both, I think Edge was just rushed out and that's why this is their "fix" for issues...
BTW, Ruben, great thinking of checking your security/virus utilities, in the past they have caused some grief for users; though in this particular instance it seems we can all produce some kind of bug with Edge, over various Win10 devices (including Windows Phone).
I was going to attempt this on my Xbox One, but it'd seem that even with the new Windows10 dashboard on it that IE is the only option.
