Brief Description 

    

W32/Dengue is a virus belonging to the W32 virus group, that affects Windows 32-bit operating systems (Windows 95, 98, NT and 2000). This is a polymorphic virus that infects Windows PE (Portable Executables) files. As W32/Dengue is a polymorphic virus, it will encrypt its code in a different manner on every infection (its signature changes every time).    
 
This virus was created by GriYo, a member of the 29A group of virus writers.
