[v9.1, v9.0] IDA Pro – World's smartest and most powerful disassembler

IDA Pro (short for Interactive DisAssembler Professional) is an excellent and extremely powerful decompiler with high efficiency and good interactivity from Belgium. It's also the best static decompiler at present (we can call it the world's top-level). Many programmers and more crackers use it and even can't do without it.
