Mutation virus engine information

MtE is technically not a virus, but an "add-on" product supplied by the person who calls himself Dark Avenger from Bulgaria. It can give any virus a "Polymorphic" ability, making it undetectable with a signature-based scanner.

Instead, an algorithmic approach is used, which may (theoretically) produce false alarms. If your virus protection indicates MtE is a virus or has MtE in the name, it may be a false or positive alarm. If you get an alarm from a data file (non-executable), it is a certain false alarm.

One known false alarm is a file called 120492_v.dxf. If you find MtE from this file, ignore it.

Several viruses are already known that make use of this "mutation engine"; therefore, there are several variants of this virus.
