MTN IS SELLING PHONES WITH Malware from the factory

Hi there, let me let you in on a story. I bought in about november last year i phone from Mtn, Hurricane Vegas. Within a week that phone stopped reading the sim, i took it back and waited 3 months for the phone to come back to me, only to find out i had to wait another 21 days, so i asked for a refund. With the refund i bought the upgrade as i desperately needed it for work as i had lost 3 months of clients already, now this is the Hurricane Atlas and its where things get really interesting. From the factory this phone has malware. From a clean set up no extra cards etc installed and factory reset, i have apps called Enginee and whone which are red flagged in my kaspersky, and by google play protection. I now have to format my phone twice a week and the longer i have this phone the more of my accounts have been compromised. I would like to know why MTN allows this? Or why no one did research on the company you get them from. I have tried to bring this up, on a few forums and facebook mtn just deleted my first comment. Absolutely Horrified that you guys pull this stuff. No info is safe, atleast facebook and google have the decency to tell you they *****ing your data.
