Well, ACTUALLY, the worm does not infect the .jpg file. In reality, the worm is a wormname.jpg.exe file. Windows/DOS only works on the last extension, so for Win/Dos, it is an .exe file! The NAME just *looks* like it is a .jpg file. So yes, you could have wormname.mp3.exe.

Open Windows Explorer, go to View->Options and make sure that "Hide file extensions for file types that are registered" is OFF, so that you can more easily see that the file is not what it appears to be. Because if that option is ON, then

worm.mp3.exe
realfile.mp3

Look like:

worm.mp3
realfile

When you view them in windows explorer, which is what most worms count on, because they are trying to confuse you.
Never did understand why hide file extensions is left on by default What was microsoft thinking as they went to sleep on their big pile of money
