how unpack this -> EXECryptor

sorry... guys... but...
I think you are all wrong.

IF they do not lie at strongbit.com, there is no "decryption" at all.

code is morphed one time, then the garbage runs - and it does NOT decrypts anything, but just does the same (among some side effects) that the original code did.

so I am afraid that you can unpack it - but you will only increase the size, you won't make it any more readable. so that - unless you have a lookup table along with some quite complicated maths - you must trace/analyse/patch the garbage; disassembling it just makes no real sense.
