The nqf file extension is associated with ESET NOD32 Antivirus, ESET's antivirus software for Microsoft Windows.
An nqf file is created when NOD32 detects potentially infected data and moves it to quarantine. The file belongs to the program's internal quarantine storage rather than being a user document.
NOD32 manages these files so that quarantined items can be reviewed, restored, or removed. The format is intended for use by the antivirus software and is not designed for independent access.
Open the nqf file through ESET NOD32 Antivirus on Microsoft Windows. Use the program's quarantine controls to review, restore, or delete the isolated item.
Do not open, edit, or rename the file manually, because it is an internal quarantine file and may contain potentially infected data.
An nqf file cannot be meaningfully converted to another document format. It is internal quarantine data, not a file intended for normal export.
If the quarantined item is safe to recover, use ESET NOD32 Antivirus to restore it. Otherwise, remove it through the program's quarantine controls.
