If Microsoft Defender Antivirus is configured to detect and remediate threats on your device, Microsoft Defender Antivirus quarantines suspicious files. If you are certain a quarantined file is not a threat, you can restore it.
Quarantined File Disappeared From The Manager
Allow messages like this: This option is turned off by default (). Turn it on () to temporarily prevent messages with similar URLs, attachments, and other properties from being quarantined. When you turn this option on, the following options are available:
In organizations with Defender for Office 365, admins can manage files that were quarantined by Safe Attachments for SharePoint, OneDrive, and Microsoft Teams. To enable protection for these files, see Turn on Safe Attachments for SharePoint, OneDrive, and Microsoft Teams.
When you select multiple quarantined files in the list (up to 100) by clicking in the blank area to the left of the Subject column, the Bulk actions drop down list appears where you can take the following actions:
An identified file is a file that has been found to be or to contain malware and has therefore been encrypted and moved to a special folder. ("Quarantine" is a scan action that you can specify when creating a Malware Scan Configuration.) Once the file has been identified or quarantined, you can choose to download it to your computer in an encrypted and compressed format. Whether or not an infected file is quarantined depends on the Anti-Malware Configuration that was in effect when the file was scanned.
If you are using a Deep Security Virtual Appliance to provide protection to virtual machines, all identified files from the Agentless VMs will be stored on the Virtual Appliance. As a result, you should increase the amount of disk space for identified files on the Virtual Appliance.
To manually restore a quarantined file, you must use the quarantined file decryption utility to decrypt the file and then move it back to its original location. The decryption utility is in a zip file, QFAdminUtil_win32.zip, located in the "util" folder under theDeep Security Manager root directory. The zipped file contains two utilities which perform the same function: QDecrypt.exe and QDecrypt.com. Running QDecrypt.exe invokes an open file dialog that lets you select the file for decryption. QDecrypt.com is a command-line utility with the following options:
To answer your question: The scanner tells QM what has been found and where, QM maintains this list along with the available actions. When you open QM it does a quick rescan and if it finds nothing in the indicated locations it prunes the list (as an aside, the scanner might have kicked off a cleanup routine which depending on the circumstances could take time - if it succeeds it also informs QM which removes the threat from the list). Thus if a threat is found in a temporary file which is subsequently deleted by the application the threat (listing) will "magically" disappear. As to the button - you have to "unlock" QM before the actions become available.

Introduction:When running antivirus software on a Backup Exec Server where a Deduplication Storage Folder is installed, binary data files required for both the functioning of the Backup Exec Deduplication Engine, as well as the integrity of the Deduplication Storage Folder itself may be deleted. This may result in the Backup Exec Deduplication Engine stopping and failing to restart, or possible corruption of backups in the Deduplication Storage Folder.What is Affected:Backup Exec Servers--with antivirus software installed--that host a Deduplication Storage Folder. The Deduplication Storage Folder functionality was introduced in Backup Exec 2010.How to Determine if Affected:If the Deduplication Folder will not come online, check to see if the Backup Exec Deduplication Engine can be started. If it cannot, check the \log\spoold.log for messages similar to the following:...June 16 08:46:07 ERR [000000000122F8E0]: 25002: _storeCheckContainers: container data file F:\DeDupFolder\data/70.bin is missingJune 16 08:46:07 ERR [000000000122F8E0]: 25002: Could not initialize DataStore ManagerJune 16 08:46:07 ERR [000000000122F8E0]: 25002: _storeReleaseCtx: pthread_cond_destroy (The system cannot find the file specified. )June 16 08:46:07 ERR [000000000122F8E0]: 25002: _storeReleaseCtx: pthread_cond_destroy (The system cannot find the file specified. )June 16 08:46:07 ERR [000000000122F8E0]: 25002: _storeReleaseCtx: pthread_cond_destroy (The system cannot find the file specified. )June 16 08:46:07 ERR [000000000122F8E0]: 25002: _storeReleaseCtx: pthread_cond_destroy (The system cannot find the file specified. )...Checking the data path (in this case, F:\DeDupFolder\data), it was discovered that the 70.bin file was missing:Note: the associated .bhd files are still present.When no antivirus software is used on the client side, the potential exists that backups made from those clients may contain files with virus signatures. In such cases, it is possible that it will end up in the Deduplication Storage Folder files where it could match a signature to any antivirus software running on that media server.It is recommended that the antivirus software be configured to exclude the Deduplication Storage Folder or at least by ensuring that it won't automatically delete or quarantine files in the Deduplication Storage Folder.
I'm trying to permanently delete items in Quarantine, not just clear the logs or history, I want the actual files removed from my computer. When I go to the Quarantine folder, I don't see any option to delete the files but I do see an option to "Clear Entries." After clicking "Clear Entries" it says:
As I mentioned, I don't want to just remove the logs and backup information. I want the actual files to be deleted from my computer. Will the "Clear Entries" actually delete the files or just the logs? If it's just the logs, then how do I delete the actual files?
So do I have to go one by one for each quarantined file and click "Remove from history" to completely and permanently delete the file from my computer? Are you sure this completely deletes the file because it does say "Remove from history", it doesn't say "Remove from computer".
If the user opts to "Remove from History", then the files associated with that item are permanently deleted (by Norton, not Windows) from the QBackup area and Quarantine. They do not exist anymore on that system. There is no rescanning to take place as the files / item do not exist in the system anymore. The rescanning of the Quarantine area is automatic and Norton does this without user intervention as part of the entire Quarantine Processing Routines. [...]
What exactly are these files in the QBackup folder? Are these all quarantined files? I have 8640 files in that folder and if they're all quarantined files, then I want to delete that entire folder. But are there also some important necessary files in that folder as well?
So for 1 of the items in quarantine, I chose the option to "Remove from history." The QBackup folder reduced from 8640 files to 8629 files. If I did the same with all of the 21 remaining items in quarantine, I think there would still be thousands of files remaining in that folder. So that begs the question, other than the items in quarantine what else does the QBackup folder contain? Anything important that can be deleted?
So if I go into Security History, go to the Quarantine dropdown, then click "Remove from history" for each and every one of the items, can someone say with certainty that the actual files will be deleted from my computer? Or is it just the "history" that's removed? It's confusing because they're calling it "Remove from history". Why don't they call it "Remove from computer" or simply "Delete File"?
Outlier:So if I go into Security History, go to the Quarantine dropdown, then click "Remove from history" for each and every one of the items, can someone say with certainty that the actual files will be deleted from my computer?
Norton removed your files by wrong? Do you know how to recover files deleted by Norton security programs such as Norton 360 and Norton Internet Security? As we already know that the antivirus applications from Norton are very good at checking, scanning, and clearing computer security threats, usually we say viruses, trojans, and malware. However, they may sometimes overdo their jobs by deleting every file that is suspected without asking. The deleted files include essential documents, pictures, and some paid programs.
In the following content, we provide you with two useful methods for Norton deleted files recovery: restoring from Norton's "Security History Quarantine" Window or recovering with data recovery software.
Usually, Norton moves files and programs that are suspected security threats to somewhere called "Security History Quarantine". Quarantined items are placed there to isolate themselves from the safe ones in the operating system, and they can be returned to its previous location by following steps.
If you find nothing in Norton's Security History Quarantine section, it means all files are permanently deleted from your HDD, in this case, there is no choice but turn to a professional data recovery program for help. EaseUS is such data recovery software that enables you to recover files deleted by Norton antivirus programs as well as another antivirus. For example, it also works on retrieving deleted files by Avast Antivirus 2ff7e9595c
