Alternative ways to Root G900H OR uninstall Trojans

My G900h was infected with some trojans (Twitter, Whatsapp and DaxApp.
I have read ways to uninstall them but I also need to root phone.
Now the trojan is smart and has killed my root.
Now when I try to open Super Su, I get "There is no SU binary installed and SuperSU cannot install it" etc.

In other words, I cant find other ways to root this G900h.

SO I ask:

1. Is there another way to root G900h 4.4.2 aside Chainfire?
2. Is there another way to uninstall these apps without root?
