If you see "crack" or "product key download" in an email subject or a website URL, it is almost certainly a trap designed to steal your passwords or lock your computer.

A highly useful feature to draft for a security product to combat this specific threat would be a module. Feature Concept: Shadow Sandboxing

: The sandbox mimics a real PC (complete with fake documents and browsing history). If the "Norton Crack" attempts to encrypt files or ping a command-and-control server, the feature kills the process instantly.
