I tried to download a file recently on a Windows 10 Fall Creators Update system using Google Chrome, Microsoft Edge and Mozilla Firefox, and could not because all blocked the file download because of a virus that was detected during the security scan. Chrome displayed "Failed - Virus detected", Microsoft Edge "[filename] contained a virus and was deleted", and Firefox simply "failed" in the user interface.
Windows Defender was the security program on the machine, and a quick check revealed that the built-in security tool was indeed responsible for blocking the file download on the machine.
I knew that this was a false positive, and the following paragraphs describe how I tried to get the file to download to the system. Select scan history afterwards. Windows Defender may list there that there are not any current threats. This may be puzzling at first, but the security program lists only threats there that require user decisions. Since the downloaded file was quarantined automatically, no user action is required which in turn means that there are not any current threats.
The list of quarantined threats is below. If you are lucky, you may see the virus that Windows Defender detected when it scanned the file download. The file name is not listed there however but the date may be sufficient to make an educated guess. A click on the row displays options to restore the file or remove it, and to display details. Details displays the file name, but it may not be enough to identify the file, as Windows Defender may display a temporary name.
Remove deletes the file from the quarantine, restore on the other hand may restore it on the system so that you may access it. The current version of Windows Defender Security Center has quite a few issues in this regard.
I mentioned the lack of details already, but it is just one of the issues that you may run into. Windows Defender Security Center limits the threats to five on that page. While you can click on "see full history" to display all items that the security program quarantined, you will notice right away that the buttons to remove or restore files are missing there. What you can try is clear the history, and retry the download. It happens that you get a failed download due to the detection of a virus, but no immediate listing under quarantined threats.
The whole process of unblocking files that you want to download that Windows Defender blocked is complicated and to a degree broken. Why are not there options to remove or restore files in the full history, why do I need to click multiple times to find out more about a threat, and why are not threats listed sometimes in the main interface where you can restore them? Very very annoying.! It appears no problem with IE but only with Edge.
For 2 days I was able to download then not again. IE, Firefox, Opera and chrome download why not Edge? I would appreciate a possible solution. I suggest you to reset Windows Components and check. Please follow the below link to know how to reset Windows Components:.
