The W32.Sonic.Worm is an email worm that appears to have originated in France. The worm emails itself to addresses in the Windows address book. Once executed, the worm attempts to download additional files, including commercial .dll files that provide emailing routines and an updated version of the worm.

The worm also creates a back door that allows remote access to the computer.
