How well Norton protects from Ransomware?

Since I am a user of Norton Security, it of course contain Antivirus. However, I have not been encountered any type of viruses, fortunately. I praise to them for good work preventing infections from stupid people who writes coding for whatever gain. Ransomware comes to mind especially so called locky. I have very little knowledge on this area since it's different from anything else. Would the product be able to detect it? Is there anything that can be prevented? Is anyone working hard at researching and find a way to trace and what not? sorry for my english but i am what i am as how i write. thanks for reading.
