Hi William
Everyone will have an opinion on this, it is something that is sometimes a person choice, because the truth is most AV software nowadays is very similar in its ability and functionality
If you want a secure system and the most compatible Security suite for Windows 10 that will not slow down your PC, then the built in Security Suite is best . . .
Windows 10 now contains a full and competent Security Suite . . .
Windows Defender has, over the last few years become a fully featured Security solution
It is on a par with paid for Anti-virus software, the virus definitions are updated regularly, it will not slow our PC down, works well with Edge and it is Free
Defender now has a new feature - Controlled Folder Access, which protects against a ransomware attack
Honestly, you do not need more protection than Defender can supply . ..
