Pre-release updates are updates that have been thoroughly tested and will be released soon. Enabling pre-release updates gives access to the most recent detection methods and fixes. However, pre-release updates might not be stable enough at all times and should not be used on production servers and workstations where maximum availability and stability is required. We recommend that basic users leave the "Regular update" option selected by default. Business users can select the "Delayed update" option to update from special update servers providing new versions of virus databases with a manually set delay.
ESET recommends that you only enable pre-release updates in situations when a pre-release update will resolve an issue you are having with your ESET product. Once you have received the update that resolves your issue, we recommend that you revert back to regular updates.
