Makes sense to me?#@$%...Comodo has Default Deny Architecture and it can prevent %99,9 malwares from your system. Comodo is hard to use because it is working with its whitelisting, if it is not in whitelist even a safe application, Comodo will sandbox it and then user thinks it is blocked. He/she does not know how to maintain automatic sandbox. They said it is not user-friendly.
Lets come my status, I am using lots of unknown open-source apps and Comodo cannot whitelist them as fast as updates of unknown softwares. Avira is much friendlier against unknown apps, because he lets everything run in your PC You can be infected if you are not using your common sense. Comodo is not a my type of product nowadays.
I love Comodo, and I use Avira
