It is becoming very important these days to have "Boot time protection" or some kind of "Preferential Loading at startup of Windows". None of the F-Secure consumer products have this feature. There are certain videos on youtube which show the importance of this feature. In one particular video the F-Secure's much capable DeepGuard is immediately able to protect against a ransomware/malware sample (but this malware sample creates a daughter .js file and a startup entry for this .js file), but due to the absense of "Boot Time Protection" is not able to stop the encryption of the user files (caused by the execution of the .js file at startup). By the time F-Secure was fully up and running after startup, user files were already encrypted.
This is a must have feature and I think F-Secure team should add this to its products on a priority basis. I believe that F-Secure is one of the best products out there (I just love its DeepGuard) and am pretty sure that F-Secure's team will definitely take some positive action on this.
