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 Internet Security records snapshots of detection engine and program modules for use with the rollback feature. In order to create detection engine snapshots, leave the Create snapshots of modules switch enabled. 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.


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.




Let the number 19959 be the most recent version of detection engine. 19958 and 19956 are stored as a detection engine snapshots. Note that 19957 is not available because, for example, the computer was turned off and a more recent update was made available before 19957 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 19956. This process may take some time. Check whether the version of detection engine has downgraded from the main program window of ESET Internet Security in the Update section.
