Sometimes you are trying to download a valid file on Google Chrome but get an error “Failed Virus Detected” even if you are downloading from a reputed website. This is a common error if you are trying to download a software crack, patch, or keygen due to Chrome security policies.
It is not recommended to download cracks or patches since they can seriously damage your Windows PC. However, if you are sure that you are downloading a legal and safe file then you can try to disable the security settings on your Windows device.
Windows 10 and Chrome have aggressive security policies that may give false-positive results, marking a valid file as a virus.
PHP files, compressed source codes, project files, or unknown but valid .exe files may get blocked by Windows security.
Fix “Failed Virus Detected” Chrome Download Error on Windows 10 & 8.1/8
If the target file is infected then Chrome won’t let you download it and remove it from the downloads folder. You can bypass the Windows security checks by disabling the security features for particular downloads.
It is recommended to enable the security setting after downloading the files.
1. Disable Windows Security
Follow these steps to turn off the Windows 10 security features-
1. Go to Start and open Settings.
2. Click on “Update & Security“option.
3. Choose “Windows Security” from the left pane.
4. Now click on “Open Windows Security” and you will get another window.
5. On the new window select “Virus & Threat Protection” from the left pane.
6. Click on “Manage Settings” under Virus & threat protection settings.
7. Now you need to “Turn Off” the following settings –
- Real-time protection.
- Cloud delivered protection.
- Automatic sample submission.
- Tamper protection.
Once you turn off these settings you will get UAC prompt, click on “Yes” to confirm.
If you are using any third-party antivirus then you need to turn off the real-time protection from the Antivirus settings.
After disabling the Security, try to download the files and check if you are able to download them or not. If not follow the next method.
2. Allow Downloaded File From Security Settings
By any chance, if disabling the Windows security doesn’t work then you can allow the downloaded file from the list of blocked files.

2. Click on Virus & Threat Protection and click on “Protection History“.
3. You will find your downloaded file on the list of blocked files.
4. Select your file and click on Allow under the Actions tab.

3. Add Exclusion to Microsoft Defender
The default security by Microsoft known as Windows defender scans for every downloaded file with its virus engine. You can exclude certain files, folders, process, and file types from the Windows defender scan.
Since the file is unable to download you can’t keep it in exclusion, so you can exclude the entire download folder and instruct Windows defender not to scan any files in the download folder.
To do this follow these steps-
1. Go to the Settings and then “Virus & Threat Protection“.
2. Select Manage Settings under Virus and threat protection settings.
3. Scroll down and find Exclusions options. Then click on Add or remove exclusions.
4. Click on Add an Exclusion and select Folder.
5. Browse the PC and select the Download folder.
6. Click on Select Folder and then Yes on the UAC prompt.
After these steps, MS Defender won’t scan any files inside the download folder. Try to download the files and check.
3. Turn Off Google Chrome Safe Browsing Feature
If you are still getting Failed Virus detected error even after turning off the Windows security then you need to turn off the Google Chrome Safe browsing feature at the same time.

4. You need to relaunch Google chrome and proceed with the download.
Turning off the Safe browsing feature will instruct Chrome not to scan for the downloaded files using Chrome smart filters.
4. Fix Virus Detected By Disabling Scan From Windows Registry
If the above 3 methods don’t help and you are facing the virus detected with your downloads then you can disable the Antivirus scan for downloaded files from the Windows registry.
1. Go to Start and search for “Regedit“.
2. Open the “Registry Editor” and navigate to the following path by expanding folder tree –
HKEY_LOCAL_MACHINE >SOFTWARE >Microsoft >Windows >CurrentVersion >Policies >Attachments
