Roll back virus signature database updates in ESET Windows home products


  • A new update of the virus signature database is unstable or corrupt
  • Roll back to the previous version of a virus signature database and suspend updates for a set period of time
  • Enable previously disabled updates if you have suspended updates indefinitely

This article applies to the following products:

  • ESET NOD32 Antivirus
  • ESET Internet Security
  • ESET Smart Security
  • ESET Smart Security Premium


If you suspect that a new update of the virus database 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 Smart Security records snapshots of the virus signature database and program modules for use with the rollback feature. In order to create virus signature database snapshots, leave the check box next to Create snapshots of update files selected. The "Number of locally stored snapshots" field defines the number of previous virus signature database snapshots stored.


  1. Open your Windows ESET product.

  2. Press F5 to access Advanced setup.
  3. Click Update, expand General and then click Rollback.

Version 9.x and earlier: click Update rollback → Roll back.

'Until revoked' is not recommended

If you select Until revoked, virus signature database updates will not resume until you manually reinstate them. We do not recommend this unless you are advised by ESET Customer Care. Disabling updates can expose your system to threats.

  1. Click OK to save your changes.

Reinstate updates

To reinstate regular updates before the selected interval you chose in step 4, expand General and then click Allow updates.
