There really isn't much need for third party AV software any more. The Windoz OS ( since Win 8?)have been shipped with "Windows Defender", which works rather well. You can lock down access to folders with the Ransomware function. Ironically , the default setting is "off". When switched on, it gets a bit fussy about what apps get to write to disk, but all you have to do is put the app in the "trusted" list if you trust it.
Haven't used anything else but Defender for some years now.
