I think it's when the virus targets only the immune system, and infects it

It would be a compromised immune system.
It can become compromised under immune suppressant drugs therefore will have decreased or no response. It is completely terminated when you die along with everything else.
The secondary immune response occurs after an antigen that has already been encountered reappears. For example, if someone had recovered from the flu and later encounters the same strain of that virus, antibodies that were made specifically for that antigen will rise dramatically with almost no lag perod.

Effector response is the phenomenon that occurs after the immune system recognizes a foreign organism. A variety of cells and molecules are then recruited to mount an appropriate response to eliminate or neutralize the organism.
The immune response is how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful.The inflammatory response (inflammation) occurs when tissues are injured by bacteria, trauma, toxins, heat, or any other cause.
Any sort of "foreign" substance can, and most often will, elicit an immune response under certain curcumstances--provided the immune system is healthy. This would include bacteria, viruses and fungi. Related: An unhealthy, or compromised immune system can act in all sorts of undesirable ways, ranging from low response to threat or injury to actually creating antibodies to attack its own system or other organs and tissue.
An innate immune response is something that you are born with, while an acquired immune response is something that your body gains throughout life...
Yes
the secondary immune response is faster and stronger than the first. the primary response also takes a few days to react with the antigen whereas the secondary immune response reacts faster to an antigen.
The pattern recognition receptors check for pathogen patterns, which decides if the innate immune system should be activated.
Looking for antigens is part of a specific immune response.
