Here you can see a comparison between eset products,eset internet security,eset smart security(premium) and eset nod32. However, remember that here smart security is the premium version, and unfortunately, our keys do not support the premium version. We hope that in the future, we could add it to our licenses.

We hope that in the future, we could add it to our licenses.
If you want to know our suggestion, we highly recommend Eset internet security because it’s the most popular version of Eset antivirus.
Indeed ESET smart security is about Eset internet security just with password manager and photo encryptor, so they are not very important features.
However, we do not recommend eset nod32 because it doesn’t have some necessary features like Banking and Payment Protection.
