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 falsely detected by ESET File Security for Linux. 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.

Manage quarantined items through the Web interface

The Quarantine screen displays a list of files stored in the quarantine folder. The list displays: the date and time of quarantine, the path to the original location of the quarantined file, reason of moving the file to quarantine, number of threats (for example, if it is an archive containing multiple infiltrations), and size of quarantined item.

Click the quarantined item to display the available actions: Restore, Restore and Exclude, Copy path, Download, Delete from quarantine.

The Restore and Exclude option is displayed only for items the detection engine evaluated as eligible for exclusion.
