Is Odin Mode bad? How do I get rid of it?

[Jefedontwantnone123]

when I do the power+volume up+menu button it goes to the download screen and

Odin Mode.
SGH-I337
Binary: Samsung Official
System Status: Official
Knox Kernel Lock: 0x0
Knox Warranty Void: 0x0
CSB-Config-LSB: 0x30
Write protection: enable
eMMC burst mode enabled

That is on the upper corner. I got an unlock code from ATT to unlock the phone but I'm trying not have it rooted or anything. Im not sure if all this Odin Mode stuff happened when I got the unlock code and I just didn't noticed. It wasn't there before until yesterday. I was freaking out cause I thought I was being hacked or something. My phone did scanned and detected "wssyncmlnps" and I heard it was nothing but then it was detected google Resolver and told me to uninstall and everything when out of wack and the custom lock icon began showing up.

Please and Thank you guys!

Odin mode is normal. It is USB boot for emergencies.

I was going crazy cause the custom lock icon never showed before. So I can just continue using my phone just fine then?

Thanks for replying as well.
