D.

Explanation:

New viruses are being introduced almost daily. The effectiveness of virus detection software
depends on frequent updates to its virus signatures, which are stored on antivirus signature files
so updates may be carried out several times during the day. At a minimum, daily updating should
occur. Patches may occur less frequently. Weekly updates may potentially allow new viruses to
infect the system.
