Choose the statement which best defines the characteristics of a computer virus.
A.
A computer virus is a learning mechanism, contamination mechanism and can exploit.
B.
A computer virus is a find mechanism, initiation mechanism and can propagate.
C.
A computer virus is a search mechanism, connection mechanism and can integrate.
D.
A computer virus is a replication mechanism, activation mechanism and has an objective.
Explanation:
Replication mechanism: To replicate a virus needs to attach itself to the right code, where it can
replicate and spread past security systems into other systems.
Activation mechanism: Most viruses require the user to actually do something. During the 80’s
and early 90’s most viruses were activated when you booted from a floppy disk, or inserted a newfloppy disk into an infected drive. Nowadays most computer virus’s come as email forwards, and
they require the user to execute.
Objective: many viruses have no objective at all, but some have the objective to delete data, hog
up memory, or crash the system.
