Normally one is the first Tools, with which a Newbie argues, W32DASM. This Tool is both easy to learn and simply serve. One hears somewhat later then of a Tool named "IDA Pro", which should be better viiieeeel than W32DASM. Fact is that W32DASM is not any longer developed further, while with IDA the pro is very much much the case. In addition fact is that IDA pro possesses some features, which make the Reverse engineering easier. But we come now finally to the actual topic.
