Keep macros from contaminating your computer

Macros are a common source of computer viruses and can be embedded in files, such as Microsoft Word documents, that you receive as e-mail attachments or input from a disk. When you open a file with a macro, Microsoft Windows will prompt with a warning that reads, "The document you are opening may contain viruses…" You must choose one of the buttons in the message in order to continue. If you are in any way unsure about the source of the file, click on "Disable Macros." This will help prevent any viruses that may be attached to the file from infecting your computer.
