Mac.Simpsons was found in the wild in June 2001. It is the first e-mail chain letter spreading under Macintosh systems. The worm is written with AppleScript. This means that although Windows or Linux users might get copies of the virus in e-mail it doesn't do anything on their systems.
Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.
More information on the scanning and removal options available in your F-Secure product can be found in the Help Center.
You may also refer to the Knowledge Base on the F-Secure Community site for more information.
Macintosh users with Outlook or Entourage e-mail programs will resend the message further if they execute the "Simpsons Episodes" attachment. Additionally, the script copies itself to "System Folder/Startup Items/Simpsons Episodes". This way the worm will be executed in the each time when the system is restarted.
The e-mail message looks like this:
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. You must have system 9.0 or 9.1 to watch the hilarious episodes, in high quality. Just download and open it. From, [your name] -- To get random signatures put text files into a folder called "Random Signatures" into your Preferences folder.
In addition, the virus will attempt to open up a web page located at https://www.snpp.com/episodeguide.html (this page has nothing to do with the virus).
