Recall that a worm is a type of malware similar to a virus except that a worm propagates by itself. Write a worm virus, where the "malicious" activity is completely harmless that can multiply itself to other files.

Recall that a computer virus is malware that relies on someone or something (other than itself) to propagate from one system to another. Write a computer virus that can be written to other empty text documents by running the batch program.

A common way to do these is through a text document that runs as a Batch program.
