Welcome to Android Central! It may be related to some other app or game you installed. This pretty shady behavior. Try uninstalling other games you installed recently, until the behavior stops. If you identify the culprit, make sure to post a negative review on Google Play to warn others of this unacceptable practice.
DT Ignite is the culprit (see this thread for more info: http://forums.androidcentral.com/samsung-galaxy-note-4/467487-t-mobile-update-contains-malware.html)
The solution is to turn off (disable) "DT Ignite" and force stop it to prevent it from being able to re-install those bloatware apps again. Then uninstall each of the bloatware apps to be rid of them.
Can DT Ignite be uninstalled with out rooting the phone.
