Windows 10: I deleted antivirus accidentally

I happened to delete the Windows 10 antivirus. Can I retrieve it in any way?

Good Antivirus + Firewall

I would never put anything Norton on my computer.

Nod32 is arguably the best antivirus. AVG is likely not as good, but it's free and at least pretty good.

Firewalls, I'd put Comodo and whatever "Tiny Personal Firewall" is named nowadays on your short list. I think Kerio might have sold it now and it's named something else. Otherwise, just put Comodo on your short list. I think the current version's ease of use has taken a step backwards, seems a bit counter-intuitive when trying to do certain things with it, but overall it does a good job and the price is right.

-> Were you going to ask how to restore it? If so then you need to re-install it, using the CD that came with the printer.
