This is the most critical part. For a commercial product like Kaspersky Endpoint Security 10, there is no such thing as a "verified free activation code" for a full, permanent license. The only official, completely free license available is a trial license. Kaspersky offers a trial license specifically for the purpose of trying out the application. This trial license has a short term (often 30 days) and automatically disables all product features upon expiration.
