More commonly, computer viruses are sent with files attached to e-mail messages. You can protect yourself, and the CCnet computers, in several ways. Some programs, such as Eudora or Microsoft Outlook, show a list of e-mail messages in one window and a preview of the selected message in another. This means that as you scroll through the list of messages they are automatically opened for you in the preview window. You should set up all e-mail programs to work this way.
Attachments are a fairly inefficient way to send information.
Consider sharing files on Zips, floppies, or using an FTP program . Simply delete these attachments without opening them, no matter what they are called. Both the CCnet Macs and PCs have virus-checking software that is easy to use. You can also manually check disks and files for viruses. Click this link for both Mac and PC directions.
