W97M/Myna.B is a macro virus operating in the Microsoft Word 97 environment. It uses the "class" method of infection – it attacks the module "ThisDocument" which is present as a standard in each Word document or template. It attacks the global template and Word documents.
Upon opening an infected document W97M/Myna.B turns off the Word anti-virus protection and attacks the active documents and the global template. The virus attacks documents when a new document is created as well as at opening and closing documents. It finds out whether a document has already been attacked by the presence of the string "MYNAMEISVIRUS" in its code.
Except replication this virus has no other manifestation.
