Hi that's also easy to break -- what if your Ransomware worked as far as Windows is concerned as a Legitimate program --say it masqueraded as Photoshop.exe --your firewall unless it had maps of every program code would not be able to say it was "Ransomware" and would allow it !!!!!.
Even simpler - a small program which re-names the Ransomware into something legit and then does its nasty business.
Firewalls are better for keeping services / ports restricted -- however once you even THINK of emails then all is lost if you aren't careful. !!!
So don't rely too much done by computer - that lulls people into false sense of security
Actually the ROUTER usually has a good firewall but people often neglect to use that.
