This virus is not directly related to the Yankee virus, although they share some code. This virus only infects .EXE files, increasing their length by 1961 bytes. When an infected program is run, the virus will search for a non-infected file. When it has been infected, the virus plays the melody, before the original program is executed. At the very end of the virus, the word "motherfucker" appears. A 1624 byte version of this virus is also known.
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.
Variant:Bandit, Enigma, Black Peter
Fairly non-interesting "laboratory" variants, not believed to exist in the wild.
In this 2051 byte variant the word at the end has been replaced by "Black Wizard", and the virus plays a different tune than the original.
