EES Polymorphic Downloader by Aphex of EES

A downloader that is impossible to detect?

Yes and no.

Anti-virus scanners detect trojans and other malware by comparing the characteristics
of the file to other known threats. CRC checks, import tables, static strings and
encryption algorithms are among the most popular methods of detection. 

A web downloader has but a single purpose and that is to download a file from a url
and execute it. There are a limited number ways to encrypt the exact same procedures
but if other operations are added to the procedures it will result in a uniqely different
file and the effectiveness of encryption is increased exponentially, raising the
difficulty of detection using these methods out of the scope of current Anti-virus
technology.

IN OTHER WORDS: generated downloader + exe encrypter = UNDETECTABLE

I recommend tElock 0.98, it is simple to use and very powerful.
