I upgraded from Windows 8.1 to 10 a few weeks back and everything was fine. About 2 days ago I started receiving a popup every time I turn the computer on stating that MS OneDrive needs to be updated. I always clicked cancel as it did not seem legit to me but I actually hit update once by mistake and upon doing so it opens up a browser and it tries to open/download OneDriveSetup.exe from https://oneclient.sfx.ms. I have screen shots from the original popup and the resulting popup if I hit update below. I tried searching for some information online but could not find anything. Is this legit or is it just some malware/Trojan?
