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 NOD32 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 Research 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).
ESET NOD32 Antivirus automatically quarantines deleted files (if you have not canceled this option in the alert window). If desired, you can quarantine any suspicious file manually by clicking Quarantine... If this is the case, the original file will not 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. Use the Restore feature for this purpose, which is available from the context menu by right-clicking a given file in the Quarantine window. If a file is marked as potentially unwanted application, the Restore and exclude from scanning option is enabled. Read more about this type of application in the glossary. The context menu also offers the Restore to... option which allows you to restore a file to a location other than the one from which it was deleted.
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 determined to be infected incorrectly (for example, by heuristic analysis of the code) 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.
