I don't see anything zone alarm related but that registry key is most certainly related to ZA, why it is even there is beyond me.
I also don't really know what the start values are, just guessing 4 is disabled as if ZA didn't exist then I don't know if the OS would be clever enough to disable it. Then when MBAM does its scan seeing it disabled perhaps it believes that to be a malicious act and flags it. Though there is nothing about that in the log, just your comment about it.
I don't generally recommend poking around in the registry as it can seriously spoil your whole day if you modify or delete anything important.
Why did you mention the changing of this value ?
e.g. does it throw up and error and if so what is the error and what application alerts you (registry protection, etc.).
Does it in anyway impede your use of the computer ?
