A Computer Worm is a self replicating program or a program that multiplies itself. Trojan horses as the name implies are hidden viruses. This helps the program to get installed in the first place.
A worm is similar to a virus by design and is considered to be a sub-class of a virus. It spread from computer to computer, and can travel without any human involvement. A worm loves to transport within your files, so it gets its way around your unit faster than any virus.
The biggest danger with a worm is its capability to replicate itself on your system, so rather than your computer sending out a single worm, it replicates until it hits critical mass and destroys your computer and everything your PC has made contact with. A worm can easily attach itself to any file, so it can transmit itself from unit to another.
