Many corporate networks have been affected by worm viruses that are spread through e-mail messages as attachments. When you open the attachment, the virus is automatically sent to random e-mail addresses in your global address book. Additionally, these viruses may copy themselves onto your computer's hard disk and any shared drives to which you have access.

Microsoft also recommends that you take the following precautions:
  • Ensure that you are running the latest version of your anti virus software.
  • Never share an entire hard disk; share only specific folders to specific users as required.
  • When you share a folder, never allow unrestricted access to it; always use a strong password to protect the share or limit access to the share to specific users.
  • Whenever possible, do not use persistent, mapped network drives (mapped drives that are reconnected each time that you log on).
