You didn't say whether your subscription for it had ended. If it has ended, don't purchase a new subscription, like the others said, download the fully free Microsoft Security Essentials. If you need an all-in-one security suite(anti-virus, firewall, etc), then try Comodo Security suite, it's free as well. Why pay when there's really great FREE software out there.
