Hey , Jian thank you for coming today. I wanted to tell you that my computer got a virus and I need help fixing it.
Wow that's terrible, do you have a firewall installed to protect your computer?
A firewall, what even is that? What do I need it for?
A part of a computer system or network which is designed to block unauthorized access while permitting outward communication. It protects your computer from malware like the one infecting your computer.
Okay I will definitely use one, thanks for the help!!
There are three different types of firewalls packet-filtering, stateful inspection, and next-gen firewalls. You should use this to help your computer and you'll be just fine.
