Answer: D
The formulation of a comprehensive antivirus policy and
education of the users are the most fundamental steps in
preventing virus attacks. These provide the broad framework
and policy from which relevant operating procedures and
practices will be developed. If no policy exists, or the
policy is not communicated, ineffective ad hoc procedures
may be practiced. The other choices are procedures within
the overall policy that direct the measures to be adopted to
prevent, detect and recover from virus attacks.
