We've talked about the Ransomware protection in prague, will there also be an extension based protection? Like for example, not only protecting a certain folder, but globally protecting a file type? For example, preventing ALL .jpg files from being modified by untrusted application. This way, you don't even have to specify a folder to protect, avast! could place extensions of commonly ransomwared file types in the list and all files would be protected regardless where they are located.
To date I'm not aware of any system that does this, they all rely on folder based protection which imo isn't enough and has too limited scope.
