Macro Virus

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In computing terminology, a macro virus is a virus that is written in a macro language: that is to say, a language built into a software application such as a word processor. Since some applications allow macro programs to be embedded in documents, so that the programs may be run automatically when the document is opened, this provides a distinct mechanism by which viruses can be spread. This is why it may be dangerous to open unexpected attachments in e-mails.
