Polymorphic packer

A polymorphic packer is a software tool, which rolls up several kinds of malware into a single package, such as an e-mail attachment, and has the ability to make its "signature" mutate over time, so it is more difficult to detect and remove. It is commonly used by hackers to insert Malware into packages which contain the user content.
