编码错误会导致不正确的程序行为(偏离需求的行为)。
By extracting the program behavior pattern which matches with virus's behavior pattern, thus the purpose of detecting unknown viruses is reached.该方法是通过抽取程序的行为模式,将之与病毒的行为模式进行匹配,达到检测未知病毒的目的。
These features make systematic changes to program behavior easy, including changes such as intercepting all calls to a method or all accesses of a field.这些特性使得对程序行为做出系统性的变更很容易,其中包括诸如拦截所有方法调用或所有字段访问这样的变更。
