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 . ..
The Free version of MalwareBytes detects a different type of threat and is a very good addition to any Security solution you use on your PC, you should use that as an on-demand scanner, in other words, don't have it running all the time, run that maybe each week or so . . .
