However, relying on such generated serial numbers is fraught with risk. First, the keygens themselves are often distributed on dubious websites and can contain trojans, spyware, or other malware. Second, even if a keygen appears to work initially, the software may later deactivate or display an “Invalid Serial Number” message after an update or after the trial period ends. Third, using a cracked serial number violates the software’s end‑user licence agreement (EULA) and is considered software piracy.
