The e-mail virus that is spreading like wildfire. It affects users of Microsoft Outlook, and sends a copy of itself to all the entries in a user's addressbook. It also coincidentally replaces all your jpeg and mp3 files with infected versions of itself. There is no known way to recover those files, unless you have a backup. One way you can prevent infection is to not open these e-mails or to use a decent operating system such as Linux, Macintosh, or FreeBSD.
