OF97/Jerk is a mildly polymorphic Office virus that infects Word and Excel. The virus borrows from WM97/Class-D, WM97/Marker-C and OF97/Crown for its infection procedure and payload.
OF97/Jerk will either print a message saying the user is a 'Big Stupid Jerk' or a message claiming to be from 'www.all.net'.
The comments and structure lead us to believe that this virus was written by a member of the notorious CodeBreakers group.
