Ransomware Protection

I was wondering if a stand-alone program exists that can be used together with my existing protection (Norton Security Suite) that will specifically target ransomeware. I checked with Symantec (Norton) and they stated their product does provide protection. Still, to be sure, I was thinking about a product that wouldn't interfere with my security suite, but would provide an extra layer of protection. I already understand the correct steps necessary to hopefully avoid this menace, but wouldn't mind extra protection, if available.
