what are some good to great anti viral protection i can use to protect my computer?

After losing a computer to damage caused by viruses and malware, I can’t stop worrying about the security of my other PCs. I recently set up a brand new machine and I would really appreciate some advice on what firewall to install and what antivirus to use. I’d also like to know if it’s safe to use a firewall while running an anti-virus or anti-malware program at the same time.

If you were using a new computer, what would you do to protect it?

How i can get the idea or recognize about the computer virus, i mean, how would i know, i have a virus in my computer?

If i have a virus in my computer, how i can eliminate it from my computer?
