RSS reader using most of my data

[Camylarde]

Hello, I have installed a data metering app and I see that one app called RSS Reader is using aout 80-90% of all my data.

I didn't set up any RSS feeds, nor can I find the app in the app list to uninstall, nor its instance to kill.

Is my phone hacked, or is there some other problem?

Thank you for helping out.
