Maltese Amoeba, Irish

Summary

Maltese Amoeba was originally written in Malta, but, strangely enough, it was first found in late 1991 in Ireland - which means that the virus was able to spread from another side of the world to another unnoticed.

Removal

Automatic action

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.

Suspect a file is incorrectly detected (a False Positive)?

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 detection database 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.

To see a world in a grain of sand,
 And a heaven in a flower
 Hold infinity in the palm of your hand
 And eternity in an hour.
 THE VIRUS 16/3/91 		 		

The virus contains also another message, which is never shown:

AMOEBA virus by the Hacker Twins (C) 1991 This is nothing, wait for the release of AMOEBA II-The universal infector, hidden to any eye but ours! Dedicated to the University of Malta-the worst educational system in the universe, and the destroyer of 5X2 years of human life.
