LG Tribute - Virus...?

[AC Question]

I have an LG Tribute form Virgin Mobile. There is a virus on it. When I try to reboot or reset it it runs a script immediately after setup and open internet browser and starts downloading weird apps and porn apps and ads start randomly showing every few second then apps start asking permission to "Install" I tried to find the app in Applications and uninstall but some app called LoveBeauty is running all of it and has somehow made itself a system app.... It only shows disable.... I want to root and delete or redo the system with a ROM but I cannot find anything to help me or that will work... Any help and suggestions gladly appreciated....
