TIMMY M9 - Root- help find custom recovery & rom

Hi! First time here.

I have a TIMMY M9 and it was giving me a LOT of problems (trojans, ad popups, install app auto and soo on).

Deleted a lot of risk app, but there are apps that keep "auto-installing"!

Like: bcfservice; documents; LocationServices; overland.

So, my question is - what do you sugest??

Thanks 4 your patience!
