Microsoft has launched an antivirus software that helps protect folders from any other application called Defender Antivirus. In a ransomware attack, all the folders and files within it are compromised and you will not be able to use them as it will be locked by another virus process. So when you add a folder to Controlled Folder Access, it provides extra security and prevents these ransomware attacks.
