I was finally able to remove the last traces of Kingroot by doing a factory re set and update. For the longest time Sony and Verizon stopped supporting the Z3v. Then for what ever reason (that I'm thankful for) Sony started to support the phone again. This updated the phone to Lollipop and removed Kingroot. Ironically I installed Kingroot to be able to update the phone and get bloat off. My problem wasn't so much with Malwarebytes always finding it in a scan, or that it was malicious, It was that you couldn't get the phone to show that it wasn't rooted even after supposedly unrooting or derooting it with Kingroot itself. Under "About Phone" it always showed up as being rooted, and some apps, like GooglePay won't install on a rooted device. Anyway, my problem has been solved and I just wanted to let people know that Malwarebytes can't remove that last bit of Kingroot that just never goes away, and to beware if you decide to try it.
