In the beginning of 1994, a new author entered the stage. Calling himself MnemoniX, this American virus writer proudly presented a new generator called MutaGen.
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.
At the moment, there are four different versions of MutaGen in distribution. Each successive version is more complex than the previous ones. Their sizes range from 1032 bytes to 1385 bytes. In MutaGen's documentation, MnemoniX criticizes the other polymorphic generators for being too unreliable and easy to detect.
MnemoniX himself has published two different viruses which utilise the MutaGen generator, but otherwise the response of the virus underground to this new generator is unknown.
