We don’t put 3rd party Antivirus on Windows 10 PC’s, the provided Defender does a decent job in my opinion, I run an IT company.
If you want to buy something to enhance security, have a look at Malwarebyres, we do put the paid for Business version onto PC’s to work in tandem with Defender.
There is a basic free version but it only scans manually doesn’t protect proactively.

If you want to get serious do a Google for “Windows 10 Standard User” - you reduce the risk of infection if you use the PC as a Standard User day to day and only logon as an Admin to do jobs like software installs and config changes. Article here:

1 – Administrator Account – An Administrator account on a Windows PC is very much like the Root account on a Unix/Linux machine.
In a nutshell, a user logged into an account with Administrator privileges can do pretty much anything on the computer. He/she can view every file on the system, change system-wide system settings, run all installed programs, add new programs, install new hardware and change the usernames and passwords of other users.
2 – Standard Account – A Standard user account cannot change most system-wide settings, run software that the account hasn’t been given permission to use, install new software or hardware that affects the entire system or change the usernames and passwords of other users.
What’s more, using a standard account will prevent most malware and other malicious programs and apps from making changes to your Windows system. And as you can imagine, that makes your system more secure.
