Mac.Simpsons was found in the wild in June 2001. It is the first email 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 email it doesn't do anything on their systems.


Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.

Technical Details

Macintosh users with Outlook or Entourage email 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 email 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 (this page has nothing to do with the virus).
