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 to help counter ransomware attacks because OneDrive can help protect your files from being encrypted by ransomware. OneDrive offers file versioning and the ability to restore previous versions of files, which can be crucial in recovering files encrypted by ransomware.

This advice is not indicative of an issue with your computer; rather, it is a proactive measure to protect your important files in case of a ransomware attack. It is always a good idea to have additional layers of protection in place to safeguard your data.
