Hello everyone, I usually back up my Microsoft Office documents, .pdfs and images to an External HD. I am afraid that, if my computer gets infected by a malware/ransomware, and it has a payload of deleting files or locking down files by encription, it could not only harm my computer, but also my files on the External HD (I keep it connected to my PC regularly, because I have many things to back up). For this reason, I'd like to make the files on my External HD undeletable, read-only and protected against any attempt to hijack/encryption by a ransomware. I wonder if there is any kind of software that could let me achieve this aim. I greatly appreciate if someone could help me out. Thanks!
