How to Keep ESET NOD32 Secure Without an Internet Connection

By 2026-2027, offline updates may shift to a monthly "Cumulative Update" model rather than daily updates, but for now, ESET releases offline updates daily at approximately 3:00 AM UTC.

An offline update package is a bundled file containing the latest virus signature databases and program module updates compiled by ESET. Instead of your antivirus software contacting ESET's cloud servers directly, you download these packages onto an internet-connected device, transfer them via removable media (like a USB flash drive), and apply them locally to the offline machine.
