How to setup Norton Firewall Win 8 for home, barebones inet

I have a win8 laptop and it seems as though there's a bunch of suspicious stuff going on it,,,,like connections to Russia, new accounts being made, my permissions changing, etc. So, I bought Nortons and want to setup a nice firewall to keep others out of my pc. My home now only has one pc, one printer I never use, a modem and a home router,,,,all i do is cruze the internet daily. I'm on it a lot each day. I have no need to share files or remote, and such. Can you show me how to setup a firewall for this? Thanks!

Also I use Chrome and office 2010...no games, no phone,etc
