You mean something like IDA Pro. Maybe I misunderstood the question.

Hi sir,

yeah like idapro but i can not analyze those cfg's. I want to write a malware detection engine based on cfgs'.

Thanks for answering.

Lookup jakstab, votum, and ROSE. Not sure if they are geared to be included in a malware detection engine. You could use them for experimentation to tune your technique. But for a production engine you would likely need to write something on your own.

Thank you sir,

you have really solved my confusion.

Thanks.

You are welcome. And if you plan to publish your findings, I invite you to submit a paper to MALWARE'2013. See http://www.malwareconference.org/.
