One of the oldest viruses known - first found in April '87. It replaces the original boot sector with itself and stores the original boot sector on track 39, head 0, sector 8. This sector is generally not used unless the diskette is almost full.
The first version of the virus contained a POP CS instruction, which only exists on 8088 and 8086 machines. This was "fixed" later, so the virus worked correctly on '286 and later machines.
As this virus is so old, several variants have been created. Some of them have been reported to format the hard disk, when they have infected a predetermined number of diskettes.
All variants of the Alameda virus replicate only when Ctrl-Alt-Del is pressed.
Alameda was probably written on an old IBM PC, by a rather lousy programmer, using the A86 assembler.
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 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.
