Macro viruses directly affect Microsoft Word and Microsoft Excel documents. There are several hundred known MS Word macro viruses. These viruses spread through Word documents. Word's advanced template system makes it an opportune environment for viral mischief. This is problematic, because people exchange a document a lot more than executables or floppy disks.
Macro viruses are also very easy to create or modify.
Although other word processors like WordPerfect and Ami Pro do not support reading Word documents, these viruses can infect them. If you suspect that you have a virus, Remain calm. In these instances, F-PROT will prompt you and advise you to replace the infected boot sector with a new one. Chances are it's a hoax.
