Hello ransomware vector

Bonjour is a part of iTunes and iCloud for Windows. You might think that you have nothing to worry about with regards to this vulnerability that's being used to spread ransomware because you don't have either of those installed, but surprisingly you may have Bonjour if you've EVER installed iTunes or iCloud because it doesn't get removed when you uninstall, so make sure to double check your installed programs.
