Finally, any "free" Pro license key found online is likely a compromised or blocked key. Comodo's licensing servers will likely reject such keys. This means you are left with a non-functional product and a potentially infected computer.

Go directly to Comodo's official website. You are looking for Comodo Internet Security Premium . This is the free, full-featured product. Do not be misled by download buttons for "Pro" trials. You want the free, non-expiring version.

When you pay for the Pro subscription, you are not paying for better virus definitions or a more powerful firewall. You are paying for supplementary services and support. The core security software is identical. Here is what the Pro edition adds:

The main differences between the free and Pro versions are the additional services (GeekBuddy and the Virus-Free Guarantee), which are not part of the free package. So, if you want the top-tier technical support and the financial guarantee, the Pro version may be worth the cost. However, many users, including members of the Comodo community, agree that the free Premium version offers more than enough protection for the average home user.
