All Free Antivirus

I’ve used Kaspersky AntiVirus and I’ve been very happy with its performance. I’ve used the Test and free version for 30 days.
Then, the key should expire. And it really happened. But now, I can’t install another free key to active it. There’s no free opition. It’s pay or nothing.
Why? Can I use the free version ( 30-day trial) one more time?

Please…somebody help me. I really wants to use it again. I really liked this AV…

Thanks!
Eddie!
