The Philo channel auto installed. I have tried to remove it by going to options and request it be removed. It doesn't work, it stays installed. I went to streaming channels and opened Philo. I chose "Remove Channel" from the menu but it does not remove. I find this very annoying because I don't like a clutter of channels on my Home page that I don't use.
Try restarting your Roku after you remove it. Also, check your subscriptions at https://my.roku.com/account/subscriptions to make sure you didn't somehow accidentally subscribe to it.
