Dark Slayer Mutation Engine
DSME was the first polymorphic generator from Taiwan. It was written by a person calling himself Dark Slayer. DSME was published in the end of 1993.
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.
Interestingly, DSME contains documentation both in English and Chinese. The author sends greetings to Dark Avenger and Nowhere Man and thanks for the inspiration he received from earlier polymorphic generators.
DSME is not as advanced as the generators produced before it. Dark Slayer admits this in his notes. The actual size of the generator is little over 2 kilobytes.
At the moment, there are few viruses known to use the DSME. One of them (DSME.Demovirus) can even be in the wild.
