Morphine is very unique application for PE files encryption. Unlike other PE encryptors and compressors Morphine includes own PE loader which enables it to put whole source image to the .text section of new PE file. This one is very powerful because you can compress source file with your favourite compressor like UPX and then encrypt its output with Morphine. Another powerful thing here is polymorphic engine which always creates absolutely different decryptor for the new PE file. This mean if your favourite trojan horse is detected by an antivirus you can encrypt it with Morphine. You will not get the virus alert again.
