Possibly malware

I became suspicious because Ive had a $2 claim pending for a month or so and the app stopped showing my new purchases and Google Now stopped showing package racking cards. So I decided to check reviews again in the AppStore on Paribus. The search function wouldnt work. I went back and tried to delete Paribus but the icon just kept moving around like someone else was owning my phone. I then restarted my phone and immediately deleted the app. The app requests your Amazon user and Password which I stupidly gave. This app doesnt feel safe.
