The authors of this virus are known. They are Lubomir Mateev Mateev and Iani Lubomirov Brankov, both in Bulgaria. Murphy is partially based on the 'Eddie' virus, but is not harmful. Inside it the following message can be found.
Hello, I'm Murphy. Nice to meet you friend. I'm written since Nov/Dec. Copywrite (c)1989 by Lubo & Ian, Sofia, USM Laboratory.
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:Murphy-2
This variant is also written by the authors of Murphy. It is a bit longer, 1521 bytes, and the message is different:
It's me - Murphy. Copywrite (c)1990 by Lubo & Ian, Sofia, USM Laboratory.
Originally this virus was reported to jump into ROM BASIC every exact hour, possibly causing some clones to "hang", but the samples available to researchers in the West produce the "Bouncing Ball" effect every time INT 18 is executed.
Variant:Amilia, AntiChrist, Bad Taste, Brothers, Cemetery, Diabolik, Erasmus, Finger, Goblin, HIV, Locker, Migram, Move, Pest, Smack, Swami, Tormentor
A series of non-interesting variants, most of which are said to be created by a person calling himself Cracker Jack. The effects vary, but the viruses are generally only "laboratory" specimens, not a serious threat in the wild.
