W32.Choke.Worm

This worm uses the MSN Messenger Service (MSNMS) program to replicate; it is the second worm that is known to do so. The worm itself does nothing more than replicate, and if it is executed on a computer that does not have MSNMS installed, it simply remains resident in memory without replicating.
