Update rollback

If you suspect that a new update of the detection engine and/or program modules may be unstable or corrupt, you can roll back to the previous version and disable updates for a set period of time. Alternatively, you can enable previously disabled updates if you had postponed them indefinitely.

ESET NOD32 Antivirus records snapshots of detection engine and program modules for use with the rollback feature. In order to create detection engine snapshots, leave Create snapshots of update files check box selected. The Number of locally stored snapshots field defines the number of previous detection engine snapshots stored.

If you click Rollback (Advanced setup (F5) > Update > Basic), you have to select a time interval from the Duration drop-down menu that represents the period of time that the detection engine and program module updates will be paused.

DIALOG_UPDATE_ROLLBACK

Select Until revoked to postpone regular updates indefinitely until you restore update functionality manually. Because it represents a potential security risk, we do not recommend selecting this option.

If a rollback is performed, the Roll back button changes to Allow updates. No updates will be allowed for the time interval selected from the Suspend updates drop-down menu. The version of detection engine is downgraded to the oldest available and stored as a snapshot in the local computer file system.

CONFIG_UPDATE_ROLLBACK

note

Note

Let the number 6871 be the most recent version of detection engine. 6870 and 6868 are stored as a detection engine snapshots. Note that 6869 is not available because, for example, the computer was turned off and a more recent update was made available before 6869 was downloaded. If the Number of locally stored snapshots field is set to 2 and you click Roll back, the detection engine (including program modules) will be restored to version number 6868. This process may take some time. Check whether the version of detection engine has downgraded from the main program window of ESET NOD32 Antivirus in the Update section.
