Fix: ‘Failed virus detected’ Google Chrome alert
Are you trying to download a certain file through Google Chrome, but you can’t successfully complete the operation? If the download process cannot be completed because it’s prevented by Google Chrome, or if when trying to open the downloaded package you receive an alert message, you need to follow the guidelines from below. We will see why your browser is blocking your access and how to fix this general Windows 10 security problem.
In most situations, you won’t be able to download or access a recently downloaded package if an antivirus program will detect a malicious file that might represent a security breach for your Windows 10 device. So, you don’t have to blame Google Chrome but your own antivirus software as it is the one showing the ‘Failed, virus detected’ alert message.
Anyway, if you know for sure that the implied file is 100% secured and that you are receiving a false-positive from your antivirus, you can fix this issue in order to resume the initial download operation. Of course, by applying the troubleshooting steps from below you can also return and use Google Chrome without receiving further security alerts. One more time, apply the guidelines from below only if you know for sure that the files which will be downloaded aren’t representing any security risks for your Windows 10 system.
How to fix the ‘failed, antivirus detected’ alert in Google Chrome
- Unblock Chrome and restore quarantined files
- Disable Windows Defender
- Scan for PUP with Malwarebytes AdwCleaner
Step 1 – Unblock Chrome and restore quarantined files
Since this security alert is usually displayed when Windows Defender is used as the only security software solution, first we will show you how to restore the blocked file:
- Open Windows Defender on your computer.
- From the main window click on History.
- In the next window click on View details.
- The files which have been quarantined will be listed there.
- Find the program that was blocked without any apparent reasons.
- You can choose to restore the implied file if you know that it can be trusted.
Now, for making sure that this file won’t get detected as potentially malicious software, you can add a particular exclusion within Windows Defender. Or, and I recommend you to do this, you can permanently disable Windows Defender.
Of course, afterward, you must choose to install a new security program in order to keep everything safe and secured all the time. But, this time choose a better security solution that gets daily updates and which can properly identify the files that are dangerous for your computer.
In that matter, one of the best antivirus programs to choose is Bitdefender. This is a paid firmware that will secure your Windows OS along with your personal files and your web browsing actions. However, if you want to use a free-distributed program instead, this article offers a proper review from where you can choose the perfect software for your particular needs.
Step 2 – Disable Windows Defender
Meanwhile, here is how you can permanently disable Windows Defender:
- Press Win+R keyboard hotkeys in order to bring the Run command.
- There, type gpedit.msc and press Enter.
- From Local Group Policy click on Computer Configuration, then extend Administrative Templates and go to Windows Components; finally, access Windows Defender.
- From the main panel double-click on Turn off Windows Defender.
- For disabling Windows Defender choose Enabled from the window that will be displayed on your computer.
- Apply and save your changes.
- Reboot your Windows 10 system in the end.
Note: Windows Defender can be disabled from System Settings too, as explained:
- Press the Win+I keyboard hotkeys.
- Choose Update & security.
- From the left panel choose Windows Defender.
- Under the Real-time protection section, you have to turn off the toggle button.
Now you can return to Google Chrome and resume your download process as you will be able to use your files without experiencing the ‘failed, virus detected’ alert message.
However, keep in mind that you mustn’t use your device without using a dedicated antivirus program. So, choose wisely in order to set up a program that has an updated virus-database; otherwise, you can experience false-positive security alert messages, just like the one which was already detailed during the lines from above.
Step 3 – Scan for PUP with Malwarebytes AdwCleaner
Finally, just for the sake of making sure there’s no a hidden, rogue extension which downloads something without your confirmation, we suggest checking for PUPs. Potentially Unwanted Programs, like adware or browser hijackers, can bring a lot of problems. One of them is false positives with the antimalware solution, completely disrupting your workflow.
Here’s how to scan for malware with the Malwarebytes AdwCleaner tool:
- Download AdwCleaner for free, here.
- Run the tool (you don’t have to install it).
- Choose Scan and wait for the procedure to finish.
- Your PC will restart and the cleaning process will continue after it boots again.
- Clean everything and restart your PC.
With that said, we can conclude this article. Don’t forget to share your thoughts in the comments section below.
