While copying files from a floppy disk, a user introduced a virus into the network. Which of the
following would MOST effectively detect the existence of the virus?
A scan of all floppy disks before use
A virus monitor on the network file server
Scheduled daily scans of all network drives
A virus monitor on the user’s personal computer
Scheduled daily scans of all network drives will detect the presence of a virus after the infection
has occurred. All of the other choices are controls designed to prevent a computer virus from
infecting the system.
