This is a harmless macro virus. It contains only one macro, but while
infecting a document of the global macros area it copies this macro with a name
that it random selected from ten variants:
AutoOpen, AutoClose, AutoNew, AutoExec, AutoExit, FileSaveAs, FileOpen,
FileClose, autoOpen, FileExit
While infecting the virus displays a MessageBox with the selected name. The
virus infects the files two and more times, as a result infected documents
and templates may contain from one up to ten macros.
