W32/Jerrym is a worm that spreads via MSN Messenger using the filename PIC1324.EXE.
On execution it creates the registry key

which it points to the executable.
It also creates a folder called C:\Messenger1324\Brain. The worm puts a file called 1ReadMe.txt, which contains removal instructions, into this folder.
