I see that ransomware are getting smarter and smarter, and I have no doubts they could be a big threat for macOS in the future as well. What are some good yet convenient ways to protect against getting ransomware? After I got a job I don't need to get software from shady sites anymore, which I assume is the biggest source of ransomware. But what else? A non-infected backup must be crucial if it actually gets infected, but after reading that backups also can get infected (http://www.computerworld.com/articl...are-had-sights-on-encrypting-backups-too.html) I'm not sure how to do it. Does it matter if I use an USB drive, wireless Time Machine, syncing apps like iCloud/Dropbox or internet backup like backblaze?
