Which of the following are characteristics of a computer virus?
A. Find mechanism, initiation mechanism and propagate.
B. Learning mechanism, contamination mechanism and exploit.
C. Search mechanism, connection mechanism and integrate.
D. Replication mechanism, activation mechanism and objective.
Solution
D. Replication mechanism, activation mechanism and objective.
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 new floppy 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.
