For most people Windows Defender built into Win10 will be fine, best to avoid Avast or AVG (There the same) as they were caught selling peoples data by default. (If you knew where to look you could turn it off)
Bit Defender is a good free Anti-Virus program, however if you are going for paid for, Sophos Home Premium has come out top over the last few years.
