I dabbed into reverse engineering a while ago (and probably will dive deeper into it seriously later) and realized it is not particularly difficult to recognize constructs in assembly code, but only for simple code such as examples. Once they go up one level, say start using a lot of win32 api, it then makes the business a lot more confusing.

That was why I decided to drop the study temporarily. I wanted to figure out exactly the OS and the type of applications (e.g. DOS virus, or Windows malware) I'd like to reverse engineer for, gain some positive engineering experience and then come back.
