A virus has infected several computers in a small office. It is determined that the virus was spread by a USB drive that was shared by users. What can be done to prevent this problem?

  • Destroy the USB drive.
  • Activate Windows Firewall.
  • Change the passwords on the computers.
  • Set the antivirus software to scan removable media.
Explanation & Hint:

To prevent the problem, the antivirus software should be configured to scan removable media. Destroying the USB drive will prevent that device from spreading the virus to other computers, but will not prevent future transmission of viruses from USB drives. Windows Firewall is a useful tool, but it does not prevent the spread of viruses.
