This virus was first reported in Israel, but a text string inside it says:


 Box 1055 Tuscambia ALABAMA USA.

This message will also appear on the screen in a box on the screen one hour after an infected program is run.

Like a few other viruses this one cannot be removed from memory by pressing Ctrl-Alt-Del. It will simply fake a "reboot" and remain in RAM.

Unlike most other resident viruses, it will not automatically infect every new program executed. When a program is run, Alabama will instead search for some other program to infect - probably so the program being executed will get the blame. It will only be infected if no uninfected file is found in the current directory.

Every Friday the virus will do something odd. It searches for a file to infect as described above, and executes it instead of the file the user was planning to execute. A bit weird ...!

One variant of this virus, Alabama-B is also known. It has been distributed in the form of a modified SDIR.COM file, but normally Alabama will not infect .COM files.


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.
