NCLR- I hope I can give you an answer to your original question without mentioning Comodo (Damn! I just mentioned it, didn't I?).
The need for an additional anti-ransomware module is inversely proportional to the quality of the base Security Solution that you have already installed. For example, for those relying on Clam AV, those folks would have a great use for an additional security module (as well as needing a Psych consult) due to the fact that ClamAV sucks.
However as you use Kaspersky TS- (a product that I think it is insane to use by Governments, but one which a Home User can be comfortable with), the need for an additional AR module is very small indeed. But please note that KTS, in addition to ANY specific AR application extent will not guarantee protection against a truly novel ransomware strain that is true zero day. But the chances that you will ever come across something like that in the first 12 hours after malware release is very, very small (remember my "Lucky" comment?).
Also, if you have viewed any of my videos (don't bother), you will see that many of the Anti-ransom applications now contain a Backup thingy- by this inclusion they are saying that they can only guarantee protection against the stuff they know, and when confronted by things that they don't know the backup is there to catch them when they fail.
So to conclude, for you I would suggest just keep on using KTS, be happy, don't obsess, and use an imaging application (wisely) with storage of the image on a removable drive- and on one that is actually removed!
And see, I never mentioned Comodo (Damn, I did it again!!!).
