The NOD32 download page shows version 2.12.3 as the current version. According to the Information page on my NOD32 Control Center, I have version 2.12.2. When I press the Update Now button, the virus signature database is updated (to 1.904) but NOD32 itself is not updated. Is there any significant difference between 2.12.3 and 2.12.2 ? Is it worth me downloading 2.12.3 and manually upgrading from 2.12.2 ?
