STEP 1
- In order to bypass the download failed, virus detected messages from Windows Defender, you should first launch Windows Defender. For that, start typing Windows in your Cortana search box and it will result in the Cortana showing you a set of search results. Click on the one named Windows Defender from the search results to launch Windows Defender.
STEP 2
- The execution of last step will launch Windows Defender window as shown in the below screenshot.
STEP 3
- From the window that opens, click on the last tab, which is the History tab. Now select the radio button corresponding to All detected items. Once you are done, click on the button named View details at the bottom of the window.
STEP 4
- Now from the list of items that gets listed under the detected items, you have to find the one that was blocked without it being an actual threat to your system. The name and path of the item, the date on which it was detected as a threat, it’s alert level and the action that was taken on the item will be shown to you by Windows Defender. Check the cell corresponding to the suspected item. This will result in the un-greying of the button named Allow item at the bottom. Simply click on it, to let the program run on your system. That’s it. Now you can try to download the file again.
If you still can’t download the file, it means that you have some other anti-virus software activated and running on your system. Proceed similarly to set exceptions on those Softwares as well, to bypass the error message. Hope you found the article useful.

How To Check File Integrity
XWith an unverified download, you might:
- Lose time if your download is incomplete or broken due to an error during the download. This is quite frequent.
- Get hacked while using Tails if our download mirrors have been compromised and are serving malicious downloads.
This already happened to other operating systems. - Get hacked while using Tails if your download is modified on the fly by an attacker on the network.
This is possible for strong adversaries.
Your BitTorrent client will automatically verify your download when it completes.
The verification below is optional for a BitTorrent download.
You have our Tails Verification extension installed.
Since December 2020, you can do the verification directly on the page. You don't need the Tails Verification anymore and can safely remove it.
See our statement about the deprecation of the Tails Verification extension.
You seem to have JavaScript disabled. To verify your download, you can either:
- Enable JavaScript.
- Compare manually the checksum of your download with the checksum of our images.
See our documentation on calculating checksums using GtkHash.
You seem to be using Internet Explorer. To verify your download, please use a different browser.

Verification successful!
Verification failed!
XMost likely, the verification failed because of an error or interruption during the download.
The verification also fails if you try to verify a different download than the latest version (4.13).
Less likely, the verification might have failed because of a malicious download from our download mirrors or due to a network attack in your country or local network.
Downloading again is usually enough to fix this problem.
Verification failed again!
XThe verification might have failed again because of:
- A software problem in our verification code
- A malicious download from our download mirrors
- A network attack in your country or local network
Trying from a different place or a different computer might solve any of these issues.

- Verify the signature of the image that you downloaded.See the Gpg4win documentation on verifying signatures.Verify that the date of the signature is at most five days earlier than the latest version: 2020-11-17.If the following warning appears:Then the image is still correct according to the signing key that you downloaded. To remove this warning you need to authenticate the signing key through the OpenPGP Web of Trust.
Downloaded File Failed Signature Verification
In macOS using GPGTools
- Download the OpenPGP signature for the Tails 4.13 USB imageOpenPGP signature for the Tails 4.13 ISO image and save it to the same folder where you saved the image.
- Download the Tails signing key and import it into GPGTools.See the GPGTools documentation on importing keys.
- Open Finder and navigate to the folder where you saved the image and the signature.
- Control-click on the image and choose Services ▸ OpenPGP: Verify Signature of File.
In Tails
Tails comes with the Tails signing key already imported.

- Open the file browser and navigate to the folder where you saved the image and the signature.
- Right-click (on Mac, click with two fingers) on the signature and choose Open With Verify Signature.
- The verification of the image starts automatically:
- After the verification finishes, you should see a notification that the signature is good:Verify that the date of the signature is at most five days earlier than the latest version: 2020-11-17.If instead, you see a notification that the signature is valid but untrusted:Then the image is still correct according to the signing key that you downloaded. To remove this warning you need to authenticate the signing key through the OpenPGP Web of Trust.

Authenticate the signing key through the OpenPGP Web of Trust
Authenticating our signing key through the OpenPGP Web of Trust isthe only way that you can be protected in case our website iscompromised or if you are a victim of a man-in-the-middle attack.However, it is complicated to do and it might not bepossible for everyone because it relies on trust relationships betweenindividuals.

The verification techniques that we present (verification in the browser,BitTorrent, or OpenPGP verification) all rely on someinformation being securely downloaded using HTTPS from our website:
- The checksum for the verification in the browser
- The Torrent file for BitTorrent
- The Tails signing key for OpenPGP verification
It is possible that you could download malicious information if ourwebsite is compromised or if you are a victim of a man-in-the-middleattack.
OpenPGP verification is the only technique that protects you ifour website is compromised or if you are a victim of a man-in-the-middleattack. But, for that you need to authenticate the Tails signing keythrough the OpenPGP Web of Trust.
If you are verifying an image from inside Tails, forexample, to do a manual upgrade, then you already have the Tails signing key.You can trust this signing key as much as you already trust yourTails installation since this signing key is included in your Tailsinstallation.
One of the inherent problems of standard HTTPS is that the trust putin a website is defined by certificate authorities: a hierarchical and closedset of companies and governmental institutions approved by your web browser vendor.This model of trust has long been criticized and proved several times to bevulnerable to attacks as explained on our warning page.
We believe that, instead, users should be given the final say when trusting awebsite, and that designation of trust should be done on the basis of humaninteractions.
Windows 10 Verifying Your Download File
The OpenPGP Web of Trust is adecentralized trust model based on OpenPGP keys that can help with solvingthis problem. Let's see this with an example:
- You are friends with Alice and you really trust her way of making sure that OpenPGP keys actually belong to their owners.
- Alice met Bob, a Tails developer, in a conference and certified Bob's key as actually belonging to Bob.
- Bob is a Tails developer who directly owns the Tails signing key. So, Bob has certified the Tails signing key as actually belonging to Tails.
In this scenario, you found, through Alice and Bob, a path to trust the Tails signing keywithout the need to rely on certificate authorities.
If you are on Debian, Ubuntu, or Linux Mint, you can install the
debian-keyring
package which contains the OpenPGP keys ofall Debian developers. Some Debian developers have certified the Tailssigning key and you can use these certifications to build a trust path.This technique is explained in detail in our instructions oninstalling Tails from Debian, Ubuntu, or Linux Mint using the commandline.Relying on the Web of Trust requires both caution and intelligent supervisionby the users. The technical details are outside of the scope of this document.

Since the Web of Trust is based on actual human relationships andreal-life interactions, it is best to get in touch with peopleknowledgeable about OpenPGP and build trust relationships in order tofind your own trust path to the Tails signing key.
After you build a trust path, you can certify the Tails signing key bysigning it with your own key to get rid of some warnings during theverification process.
