A virus is a self-replicating program, frequently with destructive side effects. Viruses
that spread via e-mail attachments are called worms. Viruses can’t travel in plain text, like e-mail messages. They contain programming,
so they need to be in binary (nontext) files. You can receive a virus as an e-mail attachment
or in a file you download. Document and spreadsheet files can contain viruses, too—
macro viruses are viruses that make use of a word processor’s or spreadsheet program’s
ability to execute instructions (macros), as well as to display a file.
