A while back I had a lot of files in the quarantine folder from running scans. I had to delete them manually from c: program files/mcafee/virus scan/quarantine. However since I did that, when I check quarantined and unwanted programs, there is never anything listed after I do a scan. When I went to look for the quarantine folder, it was not found.
- Your posting was a great help. I had a legacy Win2K server (production) that disappeared after running the infamous Windows Server Backup on my S2008 Std (not R2). I don't know what corrupted the.xml, but painstaking comparison with a good one showed some trash added on the end of the.xml file.
- How to Restore Windows Defender Quarantined / Removed Files in Windows 10 version 1803 (April 2018 update).
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
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:
Where Does Windows 10 Put Quarantined Files
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.
Advanced users only
You can toggle the ability of File Quarantine to receive updates from Apple about malware and web plug-ins.
Important: Deselecting this option disables the ability to identify new malware, and leaves your Mac vulnerable to new malware without notification.
