This is a virus for Word 97 documents and templates. It is able to replicate under the SR-1 release of Word 97. It will turn off the macro warning feature of Word 97. This virus consists of a module called "Antivirus_1_0". It is similar in features as the original WM/Cap virus in that it is designed to remove all macros which may already exist in files during the infection routine - it does this by a simple check if the module exits already in files.
This virus hooks the system event of opening Word97 by the subroutine "autoexec" thereby running its code. Other system events hooked are "filesave", "fileclose", "fileexit", "filenew", "autoopen", "fileopen" and "filesaveas". Attempts to use menu items of the same name within Word97 will run the macro code routine.
Below are comments within the macro module:
