The main function of the quarantine is to safely store infected files. Files should be quarantined if they cannot be cleaned, if it is not safe or advisable to delete them or if they are being falsely detected by ESET Endpoint Antivirus.

You can choose to quarantine any file. This is advisable if a file behaves suspiciously but is not detected by the antivirus scanner. Quarantined files can be submitted for analysis to the ESET Virus Lab.


Files stored in the quarantine folder can be viewed in a table that displays the date and time of quarantine, the path to the original location of the infected file, its size in bytes, reason (for example, object added by user), and number of threats (for example, if it is an archive containing multiple infiltrations).

Quarantining files

ESET Endpoint Antivirus automatically quarantines deleted files (if you have not disabled this option in the alert window). If desired, you can quarantine any suspicious file manually by clicking Quarantine. The original file will be removed from its original location. The context menu can also be used for this purpose; right-click in the Quarantine window and select Quarantine.

Restoring from Quarantine

Quarantined files can also be restored to their original location. To restore a quarantined file, right-click it in the Quarantine window and select Restore from the context menu. If a file is marked as a potentially unwanted application, Restore and exclude from scanning will also be available. The context menu also contains the Restore to... option, which allows you to restore a file to a location other than the one from which it was deleted.

Deleting from Quarantine – Right-click on a given item and select Delete from Quarantine, or select the item you want to delete and press Delete on your keyboard. You can also select multiple items and delete them together.


If the program has quarantined a harmless file by mistake, exclude the file from scanning after restoring it and send the file to ESET Customer Care.

Submitting a file from the Quarantine

If you have quarantined a suspicious file that was not detected by the program, or if a file was incorrectly detected as a threat and subsequently quarantined, please send the file to the ESET Virus Lab. To submit a file from quarantine, right-click the file and select Submit for analysis from the context menu.
