Today I had my Internet provider to install Internet Fiber at my place.
I've been asked whether I wanted the **antivirus service**.

I am aware you can (and should) install an antivirus on your computer.
However, I don't really get the point (and how it works) of an antivirus/firewall directly provided with the Internet connection.

My question is: **why would someone have a firewall/antivirus provided by the Internet provider, rather than locally on their own machine?**
