Strange application on my device

Hi,

Every time I deploy my application (debug, release, phone or tablet) appears another application with the same icon as mine.
When I tried to open this app, it crashes and shows a message saying that was my app who crashes...

The picture attached shows my app "Useall I2" and the other app "Ghost Here"

In the manifest generated by Xamarin I saw this on the end:

<provider android:name="mono.MonoRuntimeProvider" 
                 android:exported="false" 
                 android:initOrder="2147483647" 
                 android:authorities="br.com.useall.useall.i2.mobile.mono.MonoRuntimeProvider.__mono_init__" />
<activity android:name=".MainActivity" android:label="@string/app_name">
      <intent-filter>
         <action android:name="android.intent.action.MAIN" />
         <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
</activity>

I don't know what is this or, why Xamarin is generating this tags, but it isn't on my Manifest.xml.
I'm using the Xamarin.forms version 1.4.3.6376, Xamarin Support Library v4 version 22.2.0.0
