Also Known As:

This worm sends itself to email addresses in the Microsoft Outlook address book and also spreads to Internet chatrooms using mIRC. This worm overwrites files on local and remote drives, including files with the extensions .js, .jse, .css, .wsh, .hta, and .pwl.

The contents of most of these files are replaced with the source code of the worm, destroying the original contents. The worm also appends the .vbs extension to files with the extensions, .gif, .jpg, and .bmp. For example, image.jpg becomes image.jpg.vbs. It then copies itself to that file name.
