We are not aware of any virus that would play the song "Fur Elise". However, some PC motherboards play this tune when there is a hardware problem. Check your motherboard manual.

Musical Warning Damage Free Intelligence (D.F.I.) is a feature we have added to our newer motherboards to warn users of some classes of hardware related problems. It is a warning system on the motherboard that plays a warning tune if certain hardware problems are detected. Some users hear strange music coming out of the PC speaker and think they have been hit by a virus - they scan the hard drive multiple times and reformat it, but it just will not go away. The user now thinks that they have been infected by a virus that no virus scanning software can detect today. This is not the case at all. The standard alarm/tune/music that they may hear is a variation on "Fur Elise." Our production motherboards use this tune whereas pre-production/prototype boards may use other sound chips. There are three main sets of reasons that the alarm/tune is playing - Processor, Heatsink/Fan and Power Supply related.
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.
