- What is hardware firewall?

I can’t answer for Google Chrome specifically, but in general for browsing with any browser, you need proactive security (prevention - HIPS) and reactive security (detection - antivirus). I see from your previous posts that you have Comodo Internet Security, and that’s a great start.

You mean the Proactive Security configuration for CIS? You will get and alert if a file is created/modified that is part of your Protected Files/Folders.
Yep. Defense+ should take care of possibly malicious behaviour.
