The virus infects a document when it is opened, closed or a new one is created.
W97M/Proverb.A contains a code which is never executed. This code checks the version number of Word and if it is eight (Word 97), it would show an Office Assistant with a random message, animation and heading. Additionally, this code checks if the version number of Word is not equal to Word 97, when it would show another message box, again with a random title and text in Russian.
The W97M/Proverb.A virus code contains a lot of commented lines in Russian.
