What do you mean by "what is this?".
Your "anti-virus" (Please do yourself a favor and use Avast!) is telling you that you're about to install an app that will root your phone.
TowelRoot is completely safe and it work 100%. I've used it too, to root my phone.
Just allow the install, Google PlayStore will tell you the same ****, allow it again and after rooting uninstall the app.
Install SuperSU, update SuperSU binary (click on "normal" when it asks you), reboot and you're Gucci!
