Cybercriminals frequently disguise trojans, ransomware, and spyware as key generators. A user searching for a free license key is effectively lowering their defenses, often disabling their antivirus software to allow the "crack" to run. In a cruel irony, while attempting to fix their computer’s drivers with a pirated tool, the user may infect their system with a keylogger that steals banking passwords or ransomware that encrypts their hard drive. The "free" software can end up costing the user their identity or their entire data archive.
