Software Updates can do this too. I can't count the amount of times on the non-Nexus devices I've had to go disable new software that was installed from a "Security update"
DT Ignite is bloatware and not malware due to the definition of the words. Sure I also find it annoying having apps I don't want taking up space, 'Mal' is short for 'malicious'. So unless TD Ignite has been intentionally trying to cause you actual harm or injury, by definition it's bloatware. it can also add more bloatware (boo!) and remove bloatware as the software and developer agreements change (yay!). Also since the kickback agreements add more profit to Verizon (like they need it!) and help slow pricing increases for customers due to that profit so they don't have to always increase all costs as much by passing all costs onto bills.
