This is just side note, maybe not related to the subject but still related to Comodo, I just don't wanna setup a new thread.
Try go to download Free Comodo Internet Security 3.10 (or Comodo Anti-Virus Free or Comodo Firewall Free) and see.

No matter how you click the link from their homepage, it will the end lead you to the trial page of Comodo Internet Security Pro which require your PayPal or credit card info. They say they won't charge you for the first 30 days. But if you have no PayPal or credit card than you could not download it.

They no longer willing to offer real Free version anymore. It is a good sign. At least earning income from products is better than "other method".
