I've discovered what looks like a bug, which could expose your license information to someone who has physical access to your computer. As far as I can tell, there's no mitigating circumstances, since using a password to protect the settings, doesn't make a difference. The issue has been tested using Windows XP SP3 (Dutch) and ESET NOD32 220.127.116.11 (Dutch). Since my NOD32 is in Dutch, and I don't have an English version to check, I'll try to translate the menu options the best I can, but I can't guarantee they are 100% correct. 1. Open the NOD32 main screen 2. Go to update 3. Click "Product activation" (after 'product activated') 4. Click "Next" 5. Right now the user name is visible, but the password isn't. The box to show the password has been greyed out. However: 6. Select the password. 7. Press delete. 8. Press ctrl+z Now the show password box is clickable, and the password is being reveled to the user. Especially in shared computer environments, this is an unwanted situation (though not such an enormous security risk it would be responsible to post this in public, in my opinion).
