Sometimes it is not possible to save files integrity during the disinfection process. If a disinfected file contained important information that is partly or completely inaccessible following disinfection, you can attempt to restore the original file from its backup copy.
A backup copy is a copy of a dangerous object that is created in Quarantine when an object is disinfected or deleted by Kaspersky Internet Security.
Quarantine is a special storage area that contains backup copies of files that have been deleted or modified during disinfection. The main function of Quarantine is to let the user restore an original file at any time. Files in Quarantine are saved in a special format and are not dangerous for the computer.
In the menu bar, choose Protection > Detected Objects.
The Detected Objects window opens.
In the Quarantine section, click next to the backup copy of a file that you want to restore or remove.
The pop-up menu appears.
Select one of the following items:
To restore the file from the backup copy, choose Restore File.
To delete the backup copy of the file, choose Delete Quarantined Copy.
Important: We recommend that you not restore backup copies of files unless restoring them is absolutely necessary, because doing so could lead to a computer infection.
In the menu bar, choose Protection > Detected Objects.
The Detected Objects window opens.
In the Quarantine section, click Delete All.
By default, files are stored in Quarantine for 30 days. After 30 days, the files are deleted. You can change the maximum period for storing files in Quarantine or remove the limit entirely.
In the menu bar, click the application icon and choose Preferences.
The application preferences window opens.
On the Threats tab, in the Quarantine section, do one of the following:
To remove the limit on the storage period, deselect the Delete quarantined objects after <number> days checkbox.
To change the maximum storage period for files in Quarantine, enter a number of days in the number field of the Delete quarantined objects after <number> days checkbox.
