[KB3351] Roll back module updates in ESET Windows home products (15.x–16.x)


  • A new product update is unstable or corrupt
  • Roll back to the previous module update and suspend updates for a set timeframe
  • Enable previously disabled updates if you have suspended updates indefinitely


Click to expand

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 timeframe. Alternatively, you can enable previously disabled updates if you have postponed them indefinitely.

ESET products record snapshots of the detection engine and program modules for use with the rollback feature. To create detection engine snapshots, leave the check box next to Create snapshots of modules selected. The Number of locally stored snapshots field defines the number of previous detection engine snapshots stored.


  1. Open the main program window of your Windows ESET product.

  2. Press the F5 key to open Advanced setup.

  3. Click Update → Rollback.

  4. Select the length of time to suspend the detection engine updates from the Duration drop-down menu and click OK.

    'Until revoked' is not recommended

    If you select the Until revoked option, the detection engine updates will not resume until you manually reinstate them. We do not recommend selecting Until revoked unless you are advised to do so by ESET Technical Support. Disabling updates can expose your system to threats. Selecting this option will change your protection status to yellow.

  5. Click OK to save your changes.

    Reinstate updates

    To reinstate regular updates before the selected time interval ends (from step 4), click UpdateAllow updates.
