Going back to the four instances I put all four through ESET's Check File Reputation tool and another came back the same way with a green reputation and discovery of 1 week ago. But the other two came back saying Unavailable for both discovery time and reputation. I've scanned them and all four came back clean, but I'm still worried there's another instance of the file somewhere else that I can't find or get to or that one of the four I can get to have been hijacked and ESET submitted it because of that but can't clean it or detect the threat.
