360 Total Security (by Qihoo) offers a free antivirus version, but the “Pro” version adds features like real-time protection for ransomware, firewall, privacy cleaner, and priority customer support. Some users don’t want to pay, so they search for a “license key generator” to get Pro features for free.

These sites often ask for personal information or require you to complete "surveys" that are designed to steal your data.

For security software specifically, using a key generator is ironically one of the most insecure actions a user can take.
