Product Suggestion or company customer service contact?

I need an internet security program for my 1 home/personal PC ASAP  (presently only have built-in Microsoft firewall and a virus got in/past Microsoft Essentials masquerading as an essential Microsoft upgrade: so IT guy turned off MS Essentials.) 

A few years ago, I quit Norton 360 but want those features back (set-it-and-forget-it, internet firewall, anti-virus protection, back-up etc).  What product has taken its place?
