-
polymorphic viruses
-
stealth viruses
-
metamorphic viruses
-
boot sector viruses
-
parasitic viruses
C
Correct answer
Explanation
Metamorphic virus creates a new virus as it finds the loopholes. However, in each mutation, it rewrites itself, making the detection very complex.
-
Dormant phase
-
Propagation phase
-
Duplicating phase
-
Triggering phase
-
Execution phase
C
Correct answer
Explanation
Not all viruses can copy themselves. Some mutate to give a completely different virus program. So, it is not one of the phases of a life of a virus.
