Macintosh users are being warned of a new AppleScript-based worm/virus, called [email protected]

Symantec has confirmed that the virus attacks Microsoft email clients, including Outlook Express and Entourage. The worm sends a copy of itself with the original message to everyone in the user's address book.

Symantec says the message begins: "Hundreds of Simpsons episodes were just secretly produced and sent out on the Internet. If this message gets to you, the episodes are enclosed on the attachment program, which will only run on a Macintosh."

The worm copies itself into the Start-up Items inside the System Folder, quitting either email program will cause the application to relaunch. The worm also appears to delete all sent e-mail from the sent items folder.
