Tor Shortcut not moved/removed as McAfee quarantined firefox.exe

Tor updated yesterday and I have since re-downloaded several times but I keep getting a dialogue box saying: the 'firefox.exe' that this shortcut refers to has been removed or changed so may not work properly. Do you want to delete this shortcut. - I can't seem to access Tor in any other way on Windows 10. I download Tor to a different destination last night and managed to access via the shortcut it created but turn on my PC this morning, that shortcut has disappeared and back to the same problem again. Tor hasn't updated on my Windows 8 PC and I have no problem there.
