Because Combo Malware is a multiple malware technique, so we can use category theory, which is a very efficient tool in analysising structured information, to learn the relation and difference among malware techniques more clearly and definitly.

• Combo Malware是多种Malware技术的复合，为了更清楚、明确地了解和把握各种Malware技术间的联系与区别，引入了处理结构化信息强有力的数学工具范畴论，从范畴论的角度把Malware本身视为一个范畴，而把Malware技术特征看作范畴内的射元关系，并对Malware范畴应满足的范畴的基本性质予以论证。
