Why does my Windows Defender recommend me to setup OneDrive in case of a ransomware attack? Is there something wrong with my computer or do I have an undetected virus and how do I fix this?

Windows Defender recommends setting up OneDrive as a defense against ransomware attacks because OneDrive can help restore your files in case they get encrypted by ransomware. By syncing your files to OneDrive, you can potentially recover them even if they are compromised by ransomware. This advice is not indicative of an issue with your computer; rather, it is a preventive measure to protect your data in case of a ransomware attack.
