Antivirus Question

I have a question about Antivirus that I would appreciate advice with.

This computer is a bit over two years old. I bought it as a certified pre owned in June 2020, and since then had the "Motherboard" and I believe another piece replaced either due to hardware failure or a virus I dont remember.

Anyhow!

I have Avast Antivirus on this computer. I also had Macafee installed.

I just got a notice that says the Macafee is about to expire soon.

My question is : Should I renew the Macafee and have two separate antivirus programs on my computer, or is the Avast enough?

Any advice would be appreciated


Thanks
