File Quarantine

File quarantine-aware applications that download files from the Internet, or receive files from external sources (such as email attachments), attach quarantine attributes.

• Quarantine-aware applications include Safari, Messages, iChat and Mail.
• These attributes include date, time, and a record of where the file was downloaded from.

When you open a file received through a quarantine-aware application, OS X warns you where the file came from. You receive an alert asking, 'Are you sure you want to open it?' You should click Cancel if you have any doubts about its safety.

If you have multiple user accounts on your Mac, the user account that downloaded the file is the only user account that can remove the quarantine attribute on a file. All other user accounts can open a quarantined file, but they are still presented with an alert asking 'Are you sure you want to open it?' every time they open the file.

Known malware check

On your computer, open the folder%USERPROFILE% AppData Local Google Chrome Cleanup Tool Quarantine. Open the folder Quarantine. Right-click the file that you want to restore. I have 27322 quarantined files in McAfee quarantine forlder, when i tried to delete them, i was denied. It takes up a lot of space and i have learned that i should delete them since i have no use for them especially the old ones. What should i do? And what can i do. Thanks in advance. Open Trusted Items, select the item, and click Remove From Trust List.

Mac OS X Snow Leopard v10.6 and later also check for known instances of 'malware', or malicious software. When you open a quarantined file, OS X checks to see if it includes known malware. If so, an alert message similar to the following appears:

If you see '(file name) will damage your computer.' You should click Move to Trash.

If the file is a disk image, you should click Eject Disk Image and then delete the source file.

Tip: Click the Help icon in the lower left corner of the alert message for more information about malware.

Blocking web plug-ins

To help limit exposure to potential 'zero day' exploits from web plug-in enabled content, OS X also blocks specific versions of web plug-ins from functioning – including Java web apps, or Adobe Flash content. Typically an update to the web plug-in is available on the same day, or shortly after OS X blocks the web plug-in. Install the new update to restore web plug-in function.

Gatekeeper

OS X Lion v10.7.5 and later include Gatekeeper, a technology that allows developers to sign applications. Signed applications normally don't present an alert when you download and open them. Internet files downloaded from other applications get file quarantine attributes but without date, time, and link of the file downloaded.

The TDR Host Sensor can quarantine a file when it performs the Quarantine File action, or as part of a Host Ransomware Prevention (HRP) action. When the Host Sensor quarantines a file, it encrypts the file and stores it locally on the host.

Windows Host Sensor quarantine directory:

c:Program Files (x86)WatchGuardThreat Detection and Responsequarantine

Mac Host Sensor quarantine directory:

/usr/local/watchguard/tdr/quarantine

Linux Host Sensor quarantine directory:

/opt/watchguard/tdr/quarantine

The encrypted file remains in the quarantine directory on the host for the number of days specified in the Age Off For Quarantined Files setting. For more information, see Configure the Age Off For Quarantined Files

If you decide that a quarantined file is not a threat, you can remove the file from quarantine for up to 30 days, as long as the quarantined file remains on the host.

After 30 days you cannot undo the quarantine action, even if the quarantined file remains on the host. This is because incidents are automatically removed the system after 30 days.
