W97M/Calendar

This is a stealth macro virus written especially for Word from the Office 97 package. Its author is person nicknamed DarkChasm from the group SLAM. The virus contains seven macros with names AutoOpen, AutoClose, FileSaveAs, ToolsMacro, FileTemplates, ViewVBCode and Calendar. The first three serve for infecting, i.e. the virus infects documents when they are opened, closed and saved under a new name. But in case of infection you will not see these names. At an attempt to choose the item “Macro” in the submenu “Tools” a message announces that you are not allowed to do that. The virus turns off the Word report on macros in file. The last macro ensures the infected user is permanently informed about various holydays. We will have a look into the list of holydays with messages:
