That's... like, super disturbing. If they actually changed suddenly, then I'd be very suspicious. I mean like it's almost guaranteed that you have some form of malware that's doing it. I think the Tor bundle comes with updates disabled... but I can't be sure about that. If it does though, either you changed the settings, or something else did. Nothing has a reason to even be aware of those let alone to go changing them, unless it's a specific malware that has a reason to.So I repeat: that's like, super disturbing. Please be sure of exactly what you've observed directly if you say more about it.
