In manage apps I cannot disable torch, disable button is grey

[AC Question]

In manage apps I cannot disable torch, disable button is grey.
I force stop the torch and clear cache and go back and go into it again and its enabled. I don't want the torch.
How can I disable the app?
I tried using root but it still won't allow me.
Is there a hidden system file somewhere?

Really stuck on this one....

Just remove the app, if you are facing so much difficulties and get another torch app.

I begun this thread. I cannot remove the app. It won't allow me. I believe it's a system app but I want it gone.
