Blocked Applications will amongst other things register when a program gets blocked when it tries to access CIS processes in memory. It registers CIS protecting its self. It has always done that since its conception as Comodo Firewall v3 back in 2006. CIS up to this day log memory access attempts in HIPS Logs which most mortals do not look at. 99,999% of the programs that try to access CIS processes in memory work without a glitch without getting memory access.
Blocked Applications is not capable of unblocking memory access confusing the users further and making them worried even more. It is my strong opinion that Blocked Applications should be removed from the UI. It simply creates too much confusion.
To add to the confusion. With 1903 there is a bug with which CIS will report memory access by 32 bits programs where they are not asking for memory access.
In short. 99,99999% of the programs will work without a glitch when memory access to CIS processes is denied. Blocked Applications is not thought through enough and creates confusion making users think something is wrong where it isn’t. Allowing memory access introduces an element of risk so we only advice to allow memory access when an application needs it to function properly.
